How an impact drill differs from a rotary hammer drill

Impact drill

This tool is mainly designed for drilling in different materials. But its design includes a special percussion mechanism that allows the drill to make striking movements during operation. It resembles a hammer blow. The function helps to work with durable building materials:

This tool usually has a switch that changes from simple to impact drilling mode. It should be understood that an ordinary drill bit is not enough to crush tough materials, so a bit with a pobedite tip is used. Also, this tool is not designed for hard impacts with a large amplitude of longitudinal movement of the drill. Impact movements are made within several millimeters, so they can rather be characterized as drill vibration during work of the tool.

Drill impact force depends more on how hard you push the tool, therefore, to make a hole in a tough material, you need to apply considerable force, which is not suitable for everyone.

But drilling is not the end of this tool’s capabilities. The core drill is perfectly suited for grinding wheels, on the sticky surface of which you can attach any sandpaper. It helps to sand off a painted surface or putty on any material. You can also use attachments to turn a regular drill into a paint brush to remove paint from metal. When using a twisted wire, the processing will be rough, with a fluted wire. the finish.

Thanks to its fast rotating movements, you can mix cement or putty with this machine: simply insert the mixer fork. The number of such accessories is varied, making the drill a fairly versatile piece of equipment.

How they differ?

Impact drill and peorator, although they have common features, have a number of differences between them, on which depends on what kind of tool is better to choose for a particular type of work around the house.

Impact drill

Differences in performance in the primary function are due to differences in the components of the impact mechanism. in the peorator it is made as a complex unit of one of two types (electro-mechanical or electro-pneumatic). The second type of motor is more popular because it allows for better performance features.

The torque is transmitted from the motor by a crank mechanism or a special swinging bearing made in the shape of a sphere. The torque is converted into reciprocating action by the piston. Pressure is built up between the piston and the ram, which accelerates the ram and uses the striker to transmit its momentum to the tool.

The percussion mechanism in a drill has a much simpler design. It is made of two ratchets, one connected to the rotating chuck and the other connected to the body. If the impact mode is switched off, the contact between the ratchets is stopped by the stopper. When the mode is on, the stopper is hidden and the ratchets act together when the drill comes into contact with the surface. At this point, the chuck and drill bit create a reciprocating motion. The difference in the parts of a peorator and an impact drill determines the differences in the technical and operational features of the devices.

Functionality

The impact drill is adapted to operate with two functions: drilling with and without impact. There are a lot of drill bits for different materials that can be found on the market.

The basic tooling that is used most often:

• simple wood drill bits (including feather drill bits);
• tougher drills for metal coatings;
• lance drills for ceramics and glass (allow you to make a hole in tile);
• Core drills (made to create large holes);
• drills with pobedite tips of high strength (replace the main function of the rotary drill);
• grinding wheel (for polishing the material);
• brushes with twisted or fluted wire (for roughing and finishing);
• the mixer is used to mix construction mixtures.

Most modern full-featured models operate in three modes: chipping, rotating, and rotating with impact. the geared motor therefore works for both drilling, chiselling, shearing and piercing.

The following tasks are performed with the use of the peorator:

• drilling holes and slots in concrete, bricks, blocks;
• Wall shaving;
• hammering in rods;
• plaster removal;
• hole drilling;
• Screwing in screws, bolts and self-tapping screws;
• breaking bricks;
• knocking down tiles.

You can’t do without the torch in many situations. It works quickly, and almost no kickback is generated. When performing tasks, do not apply excessive pressure on the device, it will cause breakage. Sufficient force that can be applied to the tool is 5 kg.

Performance

This indicator of the peorator in the process of drilling is many times greater than that of an impact drill. This is primarily due to the impact energy. Lightweight rotary tools produce 1.5 kJ or more, and heavyweight tools up to 20 kJ. In a drill, this indicator is insignificant and depends on the weight that is applied to the surface. But even if the craftsman presses very hard, there is almost no increase in impact energy. This comes from the modest amplitude of the axial movement of the drill, depending on the size of the shank. the weight of the torch is also greater than that of an impact drill, even though the power capabilities of both are equal. The impact frequency of the peorator varies from 4 to 4.5 thousand blows per minute, and in powerful drills it reaches 2,000 to 3,000.

Important! If two tools with equal power drill a hole, it will be 1.5 times more than a drill. The difference in size will be even greater if a crown is used.

Total weight

The weight of both tools can vary greatly depending on the specific model and design. There is a classification of peorators according to weight:

Drills vary in weight between 1 and 4 kg.

Accessories

Peorator differs from an impact drill and the number of parts used, as well as the method of fixing them:

• when working with a drill, tooling with pobedite tips is used. Ratchets are considered the most vulnerable part to breakage, so it is not recommended to expose them to high loads;
• Both drills and drills are used in the chuck with clamps and grooves.

chuck diameter affects the ability to use small and large drills. The drill is supplied with an adapter that makes it easy to change the chuck. This is not the case with drills.

Working conditions

The main difference in tasks is in the ease of operation. 5 kg of force is sufficient for efficient work with the drill. But for the normal operation of the drill will have to attach to it a mass of 10-15 kg. In addition, the mixer hardly shakes in the hand, which makes it easier to hold and increases the accuracy of the results. This is due to the air cushion in the pneumatic mechanism. It prevents the striker from colliding with the piston and so reduces the shaking.

Service life

If you use the drill in impact mode all the time, a drill with the same drill characteristics will last much longer. The pneumatic mechanism prevents and damps vibrations, which makes the whole construction much less affected. There is also an additional safety clutch. It prevents the core drill from breaking if it should ever get jammed, for example by screwing it into a fitting.

But the ratchets in a drill are under tremendous strain during use, so they wear out quickly. Because of the strong vibrations, the entire mechanism suffers constant stress and is gradually destroyed.

Both torch and drill can be operated as a hammer. But the principle of operation looks different:

• There are several pistons in the body of the electropneumatic torch. One of them reciprocates and creates air compression. This activates the hammer, striking the small hammer which in turn strikes the tip of the drill bit. When the first of the pistons makes a reverse movement, a vacuum of air is created, and the hammers are successively brought back. The action of the accelerator is based on the reciprocating action of several pistons
• A hammer drill is not the same, it has two ratchets. One of them is connected to the body of the device and the other to the rotating chuck. When the appropriate operating mode is started, the ratchets start to touch each other and give an impact reciprocating motion to the chuck and drill bit. An impact drill works by having two ratchets closer to the chuck

The operating mechanism of a peorator is more complicated, but its efficiency is higher.

Functionality

A good pioneer can operate in 3 modes:

The difference between the drill and the gritter is the more modest capabilities. It supports only simple drilling and drilling with impact, but it cannot be used as a jackhammer. Accordingly, the tool is not suitable for chipping old coatings and reaming out niches.

Performance

The pioneer shows great effectiveness when working with masonry and concrete. First of all, it has a high impact energy. from 1.5 to 20 J depending on the model. The weight of the appliance also increases productivity.

The impact energy of a drill is, by definition, lower and is not expressed in hard values, but depends on how hard the device is pressed against the surface. Even if the material is pressed hard, the performance is still low. The axial movement of the drill will not achieve really serious values.

Sets in use

The difference between a peorator and an impact drill is in the equipment. The last device with the mode of drilling concrete and other hard surfaces is most often equipped with a conventional drill bit with a pobeditovye tip. Although this is a robust bit, it has a limited range of uses.

The core drill comes complete with nozzles for all types of work

the core drill comes with a comprehensive range of accessories. Usually includes chisels, drills, spades, and core bits. the tool can be used to drill into all kinds of stone and concrete surfaces. narrow and wide, small and deep. quickly and with little effort.

An impact drill comes complete with a special concrete drill bit

The way the accessories are fixed

In an impact drill the drill bit is simply inserted into the chuck and then clamped by rotating it tightly. In chiseling mode the mechanism may not be very reliable.

Rotary SDS vs Impact Drills. What Is The Difference Between The Two?

The drill is equipped with a cam-type chuck

The drill is equipped with a special SDS chuck, which is designed for bits with different shank diameters and has numerous notches. The system is characterized by increased reliability and very tight clamping with full torque retention.

The bits are interlocked in the chuck by pressing, with individual notches for each shank

The impact drill is noticeably weaker in terms of locking. Its mechanism does not hold the drill bit so tightly, the load on the tool body is much higher when impacting, and replacing the bit is time-consuming and requires more effort. The drill or chisel can be repositioned in just a few seconds. Due to its design, there is no excessive vibration even in the most intensive work on the housing.

Easy to use

The pehorator is precisely designed for the jackhammer function. Its design and mechanism are well thought out. To work effectively on hard surfaces, no great force is needed to press the tool against the material. A force of about 5 kg is sufficient, and good pneumatic models transmit almost no vibration to the hands.

A drill, on the other hand, is designed primarily for drilling, even if it has an impact mechanism. To make holes in stone and concrete surfaces with its help, you need to apply a force of about 10-15 kg, for some users this may be impossible.

Durability

The impact mode is additional for an electric drill, but first of all it is designed for drilling surfaces. If you use it too often, as an alternative to a jackhammer, the tool will quickly fall into disrepair. Not only the ratchets, but also all mechanisms of the device will wear out from the load.

The sledgehammer mode is the starting point for the rotary hammer. The tool is equipped with a vibration dampening system, has a special protection against breakage in case of jamming nozzles.

In construction stores you can find budget models of torches and very expensive drills. But if you compare 2 tools with approximately the same power, the device for drilling will be about 2 times cheaper.

So, we found out that there is a difference between the rotary drill and the impact drill, and it is significant. The main question you need to answer before you go to the store is what kind of material you will mostly be working with? If you take a tool for drilling in hard concrete, piercing walls, chipping tiles and other complex jobs, you definitely need a peorator. If the main task is reduced to drilling wood, metal and only occasionally concrete, the impact drill will do.

The difference between an impact drill and a geared drill

Today there are many tools of all kinds on construction markets, so it is sometimes very difficult to choose the right device for a particular type of work. Especially necessary power tools, without which it is extremely difficult to do without when making holes, recesses and openings are peorators and impact drills. 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.

Accessories and types of fasteners

In order to accurately determine the differences between an impact drill and a rotary tool, it is advisable to study the equipment and the types of fasteners used.

Drills use cam-type chucks. Such parts are required for high-quality attachment of nozzles, whose shanks have a cylindrical and hexagonal shape. Three jaws compress the drill bit at several points and create a quality fixing.

The chuck mechanisms of peorators are very different from those of rotary drills. The basis is the quick-clamping principle. The tool can move freely in a vertical position. It is this movement that creates the necessary impact force. Quick wiring is made possible by a special ball that engages in the slot in the bit’s tail.

The function of the torch

Unlike a drill, the peorator can operate in three modes: impact, rotation and a combination of these actions. That’s why the torch can be used not only for drilling, but also for reaming, creating holes and cavities of the right size. Indispensable when replacing wiring at home. An impact drill, even comparable to the torch in power, will not be able to cope with such a load.

You can use the Piezoelectric Piezoelectric Piezoe

• Make holes in hard materials (bricks, artificial and natural stone, blocks, concrete). The core drill bit is used when it is necessary to make holes of large diameter.
• Remove plaster, brick or tile from walls. Choose a chisel from the bit attachments.
• Chisel through walls at home. Need a spade nozzle.

The disadvantage of the tool is that some operations may require adapters for attachments. this increases the already considerable weight of the device and makes it less convenient, lengthening the entire design.

The Peorator is a professional tool with a well-thought-out and reliable design. It allows you to perform heavy work with high speed. When self-repairing at home most often you do not need such a powerful device, so for domestic purposes more often use an impact drill.

Design features

How to choose a concrete drill bit by sight and not to make a mistake

The peorator uses a hammer, which strikes with force, investing considerable force in hitting the chuck. It is driven in one of two ways: by a rocker bearing or with a pneumatic mechanism.

The first option is used in compact tools of medium or low power. The oscillating bearing provides a smaller displacement amplitude. This results in more frequent impacts. The oscillating bearing can break under extreme loads.

The pneumatic mechanism delivers more power, but at a relatively low frequency. However, this mechanism is more massive and more expensive. It is more suitable for use by professionals.

In a drill, the impact is ensured by ratchet gears. They are pressed against each other with their flat sides having wavy surfaces. As they rotate around a common axis, they periodically move relative to one another along the axis of rotation.

This design allows the striker to create impact forces, but results in increased wear due to the friction. The impact force in this design does not depend on the tool, but on the pressure exerted by the master.

The work of the perforator

The difference between an impact drill and a rotary hammer

Structure of the striking mechanism of the ram: 1. drunken bearing, 2. piston, 3. ram, 4. hammer (striker), 5. motor gear.

The rotary motion of the electric motor is converted by a crank mechanism or a special oscillating spherical bearing into reciprocating motion of the piston. The compression in the cavity between the piston and the ram causes the ram to accelerate and transfer its energy to the tool via the striker. drill bit, chisel, drill bit, core bit, etc.п. For more information on rotary tool construction, see the article Rotary Tool Construction.

The impact mechanism in a drill is much simpler. It consists of two ratchets, one on the body of the drill and one on the rotary chuck. to the rotating chuck. When the striker function is disabled, the ratchets are not in contact with each other because of the stopper between them. When you switch the drill to the impact position, the stopper is removed and as the drill presses against the material, the ratchets make contact by skipping against each other. The chuck and drill bit move axially in reciprocating motion.

The difference in the construction of the percussion mechanism determines the considerable difference in the performance characteristics of the torch and the impact drill.

Functionality

Chipping off tiles with the impact drill without drilling

Impact drill is used for drilling only and operates in two modes: drilling without impact and drilling with impact.

Performance

Hole diameter that can be drilled with the accelerator is approx. 1.5 times greater than with an impact drill for the same tool power. The difference becomes even greater if a core bit is used for drilling.

The tool and its fixture

The impact drill tool used to drill through concrete walls is most often a hammer drill bit.

Drills and drills are mounted in chucks, but the design of the chucks is very different between a peorator and a drill. For fast tool changes, the SDS-plus, SDS-max and SDS-top tool clamping system is used (depending on shank diameter, read more about tool chucks in the article on Peorator). The chuck is fastened in the chuck by means of specially shaped grooves.

The tool has a certain degree of freedom in relation to the chuck in the axial direction, which allows to reduce the load on the peorator in case of impacts.

In order to use usual drill bit in peorator it is necessary either to use special adapter or to change chuck for cam chuck. Thanks to the special fastening system of some models chucks can be changed quickly and easily and the drill chucks for regular drills must be included in the scope of delivery of the geared torch. If an adapter is used, you get a construction of two chucks connected in series. SDS and three-jaw chuck. The disadvantage of this variant is the lack of sufficient rigidity of the drill bit mount and its run-out during rotation.

Service life

The ratchets of an impact drill are highly stressed and wear out very quickly. Severe and severe vibration has a negative effect on all the mechanisms of the drill, putting them out of action at an accelerated rate.
