The Difference Between A Drill And A Hammer Drill

The main difference. Impact system

The most significant difference between the hammer drill and the hammer drill is the principle of the hammer system. So, for a drill, two gear mechanisms. ratchets. serve to form a blow. The tool holder is rigidly connected to the first of them, and its body. to the second. When the impact mechanism is not needed, a stopper is inserted between the ratchets, and they have no contact. When the impact mode is turned on, the stopper is removed, and the gear train converts the rotational movement of the chuck into a forward-return.

This process is just beautifully shown in the following, despite the fact that the announcer constantly calls the hammer drill a hammer drill, in fact, the shows the work of a conventional hammer drill. It’s just how the translators and the announcer know how a drill with a hammer drill function differs, they haven’t read our article :).

Main application

For the drill, the main field of application is in metal, tile and wood drilling. Well, the hammer drill is designed to overcome concrete and brick walls. Therefore, it is difficult to compare the result of the work performed by one and the other tool in terms of the hours or minutes spent, and in terms of quality. Indeed, for a drill, the impact function is only an additional one. However, as well as the drilling functions of the hammer drill. Do not neglect the instructions, using the tool "to the fullest" where only short-term operation is allowed. Sadly it will end. a good thing will break.

The difference between a hammer drill and a hammer drill. Let’s put everything on the shelves

The Difference Between A Drill And A Hammer Drill

Looking at a showcase with a neatly laid out instrument, just eyes run up, percussion drills, punchers, screwdrivers. They are all a little similar in appearance, and it seems to many that they are completely the same. Let’s find out in all the details how a drill differs from a hammer drill and in which case this or that tool can be useful to you. To begin with, we will consider why and in what cases this or that tool can be used.

What is the puncher used for?

This tool is used to break up any materials. It is often used by both cool "pros" engaged in construction and repair on an ongoing basis for several years, and home craftsmen.

Using a puncher, you can:

  • Drill a hole in concrete, brick, blocks
  • Remove the plaster;
  • Knock down the tiles;
  • Break off bricks;
  • Perform slitting of concrete walls.

Without this tool, you can’t make repairs or build a house. It is convenient to work with it. it is fast and has almost no recoil.

Device attachments can be:

  • Boers;
  • Chisels;
  • Core drills;
  • Peaks.

As for the rig, it can have a tail section of two systems. It’s either SDS Max or SDS Plus.

The SDS Plus system features four oval mounting grooves. Two of them are at the end and are open, the other two are hidden. When the shank is inserted into the chuck, it moves along the open grooves, like a guide. Special locking balls hold it in closed holes.

Drills with SDS Plus shanks.

The SDS Max system has not four, but five notches for fastening. Now there are three open grooves, so the drill holds more firmly. This system is most often used in professional tools.

The chisel attachment is placed on the hammer drill when something has to be dismantled. The lance nozzle is used for chipping walls before laying wires or for making holes in the wall. The bit will help you make a large through hole.

Functionality is important

In this regard, the hammer drill is significantly ahead of the drill. after all, it has as many as three operating modes. It’s spinning, spinning hitting and just hitting. Accordingly, with the help of an electric punch, you can not only drill the wall, but also punch it. Punching a large hole, gouging a groove for a cable, chipping off a piece of a wall. all this is within the power of such a powerful tool as a hammer drill. But the hammer drill has only two modes. standard drilling and drilling using impact. over, the force of this blow is not as powerful as that of a perforator.

Differences between a drill and a hammer drill

The difference between an impact drill and a hammer drill

Today, in the construction markets, you can find many different tools, and therefore, sometimes it is very difficult to choose the right device for a specific type of work. Rotary hammers and impact drills are especially necessary power tools, which are extremely difficult to do without when making holes, niches and openings. Often people do not distinguish them, but they have differences, both in the design of the product itself and in the specifics of working with them.

Distinctive characteristics

Like any other construction tool, the hammer drill and hammer drill have a number of distinctive features:

  • Impact mechanism

Instruments have a different scheme of the impact mechanism:

  • The hammer drill has an electro-pneumatic and electromechanical unit of the percussion mechanism. It produces impact force and provides the most effective performance parameters of this type of construction tool. In the electromechanical type, two coils cause the core to move under the influence of an electromagnetic force. The pneumatic mechanism involves the transfer of working energy through a rotating rotor that drives the piston. Due to the fact that the drill makes a reciprocating amplitude, the perforator does not require additional physical exertion or efforts, in contrast to an impact drill;
  • The drill has a more simplified impact mechanism design. It often consists of two ratchets that connect to the rotating chuck and tool body.

The existing differences in the design of the percussion mechanisms of the drill and the hammer drill determine their different technical and operational standards.

  • Operating modes (or functionality)

Modern types of rotary hammers are significantly ahead of the drill, since they have three full-fledged operating modes:

  • Single-mode or drilling. the device uses only rotations without the use of blows;
  • Three-mode. impacts without rotation (they are also called work in the jackhammer mode);
  • Dual-mode (rotation with impacts). perform drilling in combination with impacts.

Thanks to these three modes, the hammer drill can be used not only for drilling, but also for other types of work. chipping off excess material, hollowing out grooves or niches in stone walls.

The drill will not be able to provide a high level of speed, because its impact function is just one of the additions to the main

Drills have only two modes and are presented in several varieties:

  • Due to its versatility and with the presence of additional tools, an impact drill can act as a mixer, grinder, hammer drill and screwdriver. Conventional drills allow you to drill holes in wood and metal products. They also have a subspecies called "corner drills". they make holes in hard-to-reach places;
  • Drill mixers. have an extended auxiliary handle and high torque. Used to prepare a variety of building mixtures;
  • Impact. in their design they can combine the functions of drilling and impact. With their help, you can drill brick and concrete;
  • Drill-screwdrivers. in addition to their main function, they can turn or unscrew screws.
  • Total weight of the power tool

Depending on the weight, rock drills are classified as:

  • Lightweight. the weight of the structure reaches 2-4 kg;
  • Medium. within 5kg;
  • Heavy. weight exceeds 5kg.

The average hammer drill weight can range from 1kg to 4kg.

  • Equipment

The hammer drill and hammer drill differ in the number of parts used and how they are attached:

  • For drilling in a hammer drill, drills with victorious surfacing are most often used. The most vulnerable part of the tool is the ratchet. Therefore, when choosing a drill, it should be borne in mind that under heavy loads and severe vibration, they wear out very quickly;
  • In addition to drills, perforators also use drills, which are fixed in chucks using a special system of clamps and grooves of a special shape

[xyz-ihs snippet = "seredina"] Having a certain degree of freedom in the movements of the drills in the chuck, the impact load in the hammer is significantly reduced.

The possibility of using small or large drills depends on the diameter of the cartridges.

Unlike an impact drill, the hammer drill contains a special adapter that allows you to change cartridges if necessary.

Another positive point when choosing a hammer drill is the effect of less vibration on the hands of the master due to the softening air cushion located in the pneumatic percussion mechanism.

  • Performance

Determined by the value of the impact energy. With a hammer drill, it fluctuates between 1.5-20J and is always an order of magnitude higher than that of an impact drill. This largely depends on the mass of the device and the pressing force of the master. The technical characteristics of perforators may also indicate the frequency of blows per minute: from 4 to 4.5 thousand. Impacts in more powerful models and 2-3 thousand in less powerful.

  • The cost

Taking into account the same power of the tools, the hammer drill is always much more expensive in comparison with the price of a hammer drill. However, one should not forget that the rock drill belongs to the category of professional tools, so its cost fully justifies itself. drilling speed and durability in operation.

Remember that when working with a hammer drill, you need to apply three times less force than when using an impact drill

. Tool selection criteria

When choosing a power tool, you should pay attention to the following criteria:

  • Power. the higher the power level, the more comfortable the tool is to use.
  • Availability of speed control.
  • Equipped with additional attachments.
  • Idling speed (rotation speed).
  • Scope of speeds (one, two, three, etc.).
  • Possibility of movement (rotation) in both directions (reverse movement). In some cases, this helps to remove a stuck drill.
  • Possibility to create holes of different diameters in different building materials.

The main purpose of the tools

The main difference between a hammer drill and a hammer drill lies in their functional purpose:

  • For a hammer drill, this is drilling in materials that are not very dense (wood, plastic, soft metals, etc.). In addition, the percussion functions of the drill allow you to drill even concrete and brick. With conventional models, the working effect produced largely depends on the pressure of the master. Therefore, to obtain an optimal and acceptable impact energy, the pressure force must reach 10-15 kg;
  • For a hammer drill, this is chiselling. The impact function is built into the hammer drill initially, as well as drilling. At the same time, it is not recommended to put pressure on the perforator, as this can lead to tool breakage. The maximum pressure limit should be no more than 5 kg.

Depending on the general functions, a hammer drill can perform a fairly wide range of work compared to the functionality of a hammer drill:

  • Chipping and driving in of rods;
  • Slitting concrete walls;
  • Drilling of various types of surfaces, including wood, concrete and steel;
  • Chips, chips of bricks, knocking down tiles, removing plaster and making holes;
  • Driving bolts, screws or self-tapping screws

What to choose?

The hammer drill and hammer drill can function as each other. However, replacing a hammer drill with a drill can lead to rapid wear.

The choice of a tool directly depends on the material with which it will be necessary to work: In such a matter, it is better to proceed from the purposes for which the construction tool is purchased. If you need to do household chores, a functional drill will be enough. For long, constant and voluminous work, it is better to use a rotary hammer.

  • If the work involves the processing of concrete structures or objects made of similar materials, then it would be preferable to choose a perforator;
  • The drill is suitable when working with wood or steel products.

The main differences of the tool

So, the main purpose of the rock drill is to drill holes in durable materials such as concrete, artificial and natural stone, and brick. This is possible thanks to extra strong drills, which replace drills in the construction of the hammer drill. If you do not really go into technical details, then we can say that one of the characteristic differences between a drill and a hammer drill is the principle of operation. That is, the hammer drill mechanism is configured for impact, while the drill operates on the principle of rotation. Simply put, a hammer drill knocks out holes, and a drill drills them. The impact principle, on the basis of which the hammer drill works, makes it possible to use the tool in work with high-strength building materials.

In addition, it is worth highlighting the differences in electricity consumption. Despite the impact principle of work, the hammer drill requires much less power, which means that the tool is economical in energy consumption. But here it is worth noting that the hammer drill is still a professional tool and is more often used in large-scale construction than in cosmetic repairs. Agree, not every repair requires gouging concrete reinforced walls or knocking holes in the stone. Therefore, the hammer drill is most often used in large-scale construction.

Drill benefits

A modern drill is a multifunctional tool, which is often equipped with an impact function. In addition, some models provide the ability to use perforating drills in the drill. But at the same time, a special attachment must be used, otherwise the instrument can be damaged. Yet the main purpose of the drill is to drill soft building materials such as chipboard, wood and iron.

In home construction, some drill models can be used in a wider field of work. The drill can be easily converted into a pump, construction mixer or nibbler thanks to special additional attachments.

Unlike a hammer drill, a drill is a more accurate and multifunctional tool, which allows you not only to work with various materials, but also drill holes of a rather small diameter.

Summing up the main differences between a drill and a hammer drill, it is impossible to say unequivocally which tool is more in demand in construction. Depending on the tasks and materials to be processed, it is advisable to use both a hammer drill and a drill. The main thing is. Clearly navigate the main purpose of each instrument.

Performance

At the same power of the tools, the hole diameter that can be obtained with a hammer drill is approximately 1.5 times the diameter that can be obtained with an impact drill. The difference increases even more if a crown is used for drilling.

What is the difference between an impact drill and a hammer drill

Functionality

The hammer drill is used only for drilling holes and works in two modes: drilling without impact and drilling with impact.

Impact mechanism

The rotational motion of the electric motor is converted by means of a crank mechanism or a special swinging spherical bearing into a reciprocating piston motion. Under the action of compression in the cavity between the piston and the ram, the latter accelerates and transfers its energy to the tool through the hammer. Drill bit, chisel, drill bit, bit, etc. For more information about the punch device, see the article Punch device.

The impact mechanism of the drill is much simpler. It consists of two ratchets, one of which is connected to the drill body, the other. With rotating chuck. When the impact function is disabled, the ratchets do not contact each other due to the stopper located between them. When the drill is switched to the impact position, the stopper is removed and when the drill is pressed against the material, the ratchets begin to contact, slipping over each other. In this case, an axial reciprocating movement is given to the chuck and drill.

The difference in the design of the percussion mechanisms determines a significant difference in the technical and operational characteristics of the hammer drill and the hammer drill.

Tool and fastening

The hammer drill tool used for drilling concrete walls is most often a winnowed drill bit.

In a hammer drill and a drill, drills and drills are mounted in chucks, however, their design is very different for a hammer drill and a drill. For a quick tool change, the rock drills use the SDS-plus, SDS-max and SDS-top tool clamping system (depending on the shank diameter, for more information about hammer drill chucks, see the article Punch). Fixation in the chuck takes place using specially shaped grooves.

In a hammer drill, the tool has a certain degree of freedom in relation to the chuck in the axial direction, which makes it possible to reduce the load on the hammer during impacts.

In order to use a conventional drill in a hammer drill, you must either use a special adapter, or change the chuck to a cam one. In a number of models, thanks to a special mounting system, the change of chucks is quick and easy, while the chuck for a conventional drill must be included in the perforator kit. When using an adapter, a design is obtained from two series-connected cartridges. SDS and three-cam. The disadvantage of this option is the lack of sufficient rigidity of the drill attachment and its runout during rotation.

Working conditions

How does a hammer drill differ from a drill

A hammer drill is needed to drill a hole in a brick or concrete wall. Also for this purpose, you can use an impact drill, the work of which is arranged in such a way that the drill, crown or drill rotates simultaneously and impacts in the axial direction.

But it’s worth noting that this is where the similarities end. The first and main difference between the hammer drill and the hammer drill is that the hammer drill is needed for chiselling, and the hammer drill is needed for drilling.

The difference between a hammer drill and a drill is that the hammer drill has an impact mechanism, which is a complex unit, the operation of which is possible in an electromechanical and electro-pneumatic design. Often, an electro-pneumatic type of perforator is produced, since pneumatics can improve the operating parameters of the tool.

The drill contains a percussion mechanism that is simpler in structure. There are two ratchets here. The first ratchet connects to the body and the other connects to the rotating chuck. If you turn off the hammer function, then the ratchets stop contacting each other.

If you switch the drill from drilling mode to impact mode, the stopper is removed. During operation, the chuck and drill move in the axial and translational directions at the same time.

Impact drills can only work in two modes: the first is drilling without impact, the second is drilling with impact. over, with a puncher, you can make niches and grooves in the wall, remove excess material from the surface.

In terms of productivity, the hammer drill is far behind the hammer drill. The latter has a sufficiently high impact energy. The impact energy of the drill is very small and depends on the pressing force of the tool against the material being processed. The impact force of the drill will be small, even if you press it strongly, since it has a small amplitude of drill movement in the axial direction.

Various tools and mounting methods are used for the hammer drill and drill. Drills and drills are mounted in chucks for both representatives, but the design is very different. The rock drill has a clamping system for quick tool changes. These include SDS-plus, SDS-max and SDS-top. The instrument is fastened by means of special shaped canafs.

Today, hammer drill manufacturers equip the kit with special adapters and chucks for a conventional drill.

The difference between a hammer drill and a drill If you use an adapter, a structure is formed that does not firmly fasten the drill, and accordingly, the beating during rotation will not pass properly.

The difference between a hammer drill and a drill also lies in the fact that work with a hammer drill is much easier. The clamping force for the punch is 5 kg, for the drill. 10-15 kg.

Since the rock drill has less pressing force, there is less vibration in the hands. Thanks to the softening air cushion in the pneumatics, the firing pin and the piston do not collide with each other, which means that the hands will be less tired.

The hammer drill has a special safety clutch that protects the tool from breakage in some cases, for example, if the drill hits the reinforcement.

With a drill, the ratchets will work without a sparing mode, therefore, these parts wear out quickly. The cost of tools differs at the same power. The price of a hammer drill is twice the price of a drill.

Punch device

The controls are located on the body of the tool, as can be seen in the following photo:

The internal structure of the punch cannot be understood without disassembling it.

    The following main components are hidden in the plastic case:

  • Electric motor;
  • Safety clutch;
  • "Drunk" bearing;
  • Flying piston;
  • Cartridge.
  • The principle of operation of the hammer drill consists in converting the rotation of the electric motor into the shock-rotational movement of the nozzles. The electric motor drives the rest of the hammer drill mechanism.

    The safety clutch ensures the safety of specialists during work. Drunken bearing drives the piston, creating an impact force, and the chuck secures the nozzles.

    Impact drill and hammer drill what is the difference

    Externally, the main difference between a hammer drill and a hammer drill is in weight and dimensions. The modern impact drill has the same dimensions as the hammerless counterpart, and the hammer drill is heavier and larger.

    Also, most drills have a pistol-like layout, with a horizontal motor. Among rock drills, the design with a vertical engine is also very common. This option allows you to shift down, closer to the hands of the worker, the center of gravity, thereby making it easier to work with a heavy tool.

    Internally, the modern rock drill and hammer drill differ much more. An impact drill, to create not only rotational, but also reciprocating movements, is equipped with a unit consisting of a pair of toothed ratchets. In simple drilling mode, these two ratchets do not interact with each other in any way.

    A hammer drill is a more complex device equipped with a complex percussion mechanism. Often separate shafts are used to drive the drill and generate jolts (as opposed to an impact drill).

    The shock movement is transmitted by an eccentric mechanism or a swinging ("drunk") bearing to the piston, striking the striker (ram). The latter transfers the impact energy to the chuck with a drill or drill located. The torque is usually taken from a separate shaft.

    Knowing how a rock drill and an impact drill work, the difference between the two becomes clear. Due to its design features, the drill has a low impact impulse. When working with very hard materials, the recoil significantly affects the ratchet teeth, leading to their heating and accelerated wear.

    Rotary hammers have another drawback: their large dimensions make the work in the drilling mode more difficult, more energy is required from the worker. A drill, weighing 1.5-2 kg, is much more convenient to hold than a 4-5 kg ​​perforator. And this tool consumes more electricity (per unit of time).

    Even knowing the pros and cons, it is quite difficult to decide which is better. a hammer drill or an impact drill. In fact, the question itself in this form is incorrect and is a classic example of the "battle of an elephant with a whale".

    If there is a choice of the type "hammer drill or hammer drill". which one to prefer. depends only on the specific conditions of use. Just as a bus is good for transporting people, and it is more convenient to transport rubble on a dump truck, so these tools are good for everyone in their business.

    Impact drill device

    In order to drill a hole not only in wood and metal, but also in brick and concrete, in addition to rotational movements, translational percussion is required. Impact is designed to crush the material while drilling pulls the chips out and helps the drill bit into the material.

    That is, for efficient drilling of hard materials, it is necessary that rotational and impact movements occur simultaneously.

    Impact drills consist of several main components: a tool body, an electric motor, a gearbox, bearings, buttons for switching on and adjusting revolutions, a chuck.

    This impact system is called mechanical. And since the ratchets are subject to a lot of friction as they spin, they gradually wear off. With active use of the shock mode, this process will be accelerated many times over and, as a result, the shock function will come to naught.

    The main function of the hammer drill is still drilling, so the control mechanism of the hammer drill is provided with a speed regulator. This switch is essential for efficient handling of various materials and consumables.

    For example, for drilling a brick, the regulator is recommended to be set at a large number of revolutions, for drilling tiles, on the contrary, at a small number. The same analogy can be drawn using different attachments.

    Most manufacturers in parallel produce tools with two types of chucks. with key (cam) and keyless (keyless). Their main difference is that a special clamping wrench must be used to clamp the key chuck.

    READ  How to Drill a Brick with an Ordinary Drill

    Whereas, to clamp the keyless chuck, it is enough to tighten it by hand. Both systems have their own advantages and disadvantages. Keyless chuck will allow the operator to quickly change working attachments, while the key chuck will allow you to fix these attachments much more reliably.

    Reverse is also a very important system for the efficient operation of the hammer drill. By switching this mode, the operator forces the tool to rotate the working attachments in the opposite direction. This function is essential when the working attachment is jammed in the material.

    In order not to damage the hole, pulling the drill out of it is enough to turn it in the opposite direction on the reverse. In addition, the reverse function is perfect for those cases when the operator will use the drill as a screwdriver. It will help not only to tighten the threaded fasteners, but also to unscrew them.

    What is the difference between an impact drill and a hammer drill

    When drilling holes in brick or concrete, a hammer drill or impact drill is usually used, in which the rotation of the drill (drill, crown) is accompanied by blows in the axial direction. These tools are considered to be similar in their action, but in fact, their differences are no less than similarities.

    What is the difference between a hammer drill and a hammer drill? First of all, in their main function, for a hammer drill it is chiselling, for an impact drill it is drilling.

    The difference in the main function determined the difference in the schemes of the percussion mechanism. In a hammer drill, the latter is a rather complex unit that exists in two versions. electromechanical and electro-pneumatic. The most common electro-pneumatic type, providing the best tool performance.

    The figure below shows a diagram of an electro-pneumatic rock drill.

      Punch hammer mechanism device:

  • 1. drunk bearing;
  • 2. piston;
  • 3. ram;
  • 4. drummer (striker);
  • 5. engine gear.
  • The rotary motion of the electric motor is converted by a crank mechanism or a special swinging spherical bearing into a reciprocating piston motion.

    Under the action of compression in the cavity between the piston and the ram, the latter accelerates and through the hammer transmits its energy to the tool. drill, chisel, drill, crown, etc. For more information about the punch device, see the article Punch device.

    When the drill is switched to the impact position, the stopper is removed and when the drill is pressed against the material, the ratchets begin to contact, slipping over each other. In this case, an axial reciprocating movement is given to the chuck and drill.

    The difference in the design of the percussion mechanisms determines a significant difference in the technical and operational characteristics of the hammer drill and the hammer drill.

    Modern full-featured rock drills have three modes of operation: impacts without rotation (work in the mode of a jackhammer), rotation without impacts, rotation with impacts. The hammer drill can be used not only for drilling various materials, but also for other work. hollowing out niches or grooves in stone walls, chipping off excess material, etc.

    Punch mode switch (Bosch). Between drilling with impacts and impacts without drilling. position for changing the position of the chisel (Vario-Lock).

    The hammer drill is used only for drilling holes and works in two modes: drilling without impact and drilling with impact.

    The performance of the hammer drill when drilling stone materials is several times higher than that of an impact drill. This is primarily due to the higher impact energy. For a hammer drill, it ranges from 1.5 J for light models to 20 J for heavy ones. Drill impact energy is negligible.

    It depends on how hard the tool is pressed against the material. Even if the pressing force is large, the impact energy still remains low due to the small amplitude of the axial movement of the drill, equal to the height of the ratchet tooth. The hammer’s performance is also enhanced by its weight, which exceeds the weight of a hammer drill of the same power.

    At the same power of the tools, the hole diameter that can be obtained with a hammer drill is approximately 1.5 times the diameter that can be obtained with an impact drill. The difference increases even more if a crown is used for drilling.

    There is a big difference between an impact drill and a hammer drill in the tools used and how they are attached. The picture below shows the most commonly used punching tools.

    The hammer drill tool used for drilling concrete walls is most often a winnowed drill bit.

    In a hammer drill and a drill, drills and drills are mounted in chucks, however, their design is very different for a hammer drill and a drill. For quick tool change, the rotary hammer drills use the SDS-plus, SDS-max and SDS-top tool clamping systems. Fixation in the chuck takes place using specially shaped grooves.

    In a hammer drill, the tool has a certain degree of freedom in relation to the chuck in the axial direction, which makes it possible to reduce the load on the hammer during impacts.

    When using an adapter, a design is obtained from two series-connected chucks. SDS and three-jaw. The disadvantage of this option is the lack of sufficient rigidity of the drill attachment and its runout during rotation.

    A hammer drill is much more durable than a hammer drill. if you use the latter with a hammer function. Its pneumatics provide significantly less vibration and gentle conditions for the operation of all its mechanisms. The tool has a safety clutch to protect it from breakage in the event that the drill gets jammed in the hole. for example, when it hits the reinforcement.

    Impact drill ratchets are heavily stressed and wear out very quickly. Strong, hard vibration negatively affects all the mechanisms of the drill, disabling them at an accelerated rate.

    With the same power (but not the impact energy, which is much higher for a hammer drill), a hammer drill costs much (1.3-2 times) more than an impact drill.

    The question. which is better, a hammer drill or a hammer drill. has no definite answer. It all depends on the purpose for which the instrument is purchased. The hammer drill is a tool for drilling and chiselling concrete and brick walls. It is acquired in cases where there is a need to drill a large number of holes in concrete or brick.

    If you need to make cavities (grooves) in concrete walls for wires, sockets and switches, then you need a puncher. At the same time, it is not necessary to buy a punch, it may be more profitable to rent it.

    Sds plus sds max difference

    Despite such a variety of convenient and practical SDS shanks, the following are common in construction: the SDS Plus holder and drill for simple household tasks and its "brother" SDS Max chuck and drill for heavy professional work.

    The unique technology of construction and fastening of drills in the tool makes them indispensable in our time: the SDS system has proven itself as a reliable innovation that extends the operational life of the working tool, and allows you to maximize the functionality and power capabilities of the tool without loss.

    And the modern design of drills makes them convenient and practical for working with household and professional percussion tools. The SDS Plus concrete drill is used with small domestic rock drills: 2-4 kg, they are used in domestic and industrial conditions for drilling holes in hard materials up to 26 mm deep.

    The structure of the SDS shank is easy to remember: there are four grooves on the profile: 2 open and the same number of closing ones. Open ones serve as guides for entering the chuck (40 mm deep). Locking balls fit into the closed slots, securing the drill in the tool.

    Drills are available in commonly used diameters. 6mm, 8mm, 10mm, 12mm.

    Breaking drill SDS Max. already visually different. The diameter of the SDS Max drill is twice that of SDS. from 20 mm, and is used as a working part of heavy rock drills in construction and when dismantling surfaces.

    Such drills are relevant when gouging walls, ceilings, concrete, foundations, asphalt and other hard surfaces.

    The design of the sdc max is a bit complicated: the length of the drill allows you to insert it into the hammer drill 90mm deep, and the fivefold number of grooves (of which 3 are open and guides, and 2 are closed and holding) ensures reliable holding and free movement of the drill.

    To work with this SDS Max concrete drill, special SDS Max rotary hammers are required.

      Models with special demand among professionals are produced by the following brands:
  • Hilti;
  • Bosch Professional;
  • Dewalt;
  • Sparky Professional.
