How is an impact drill different from a hammer drill?

The principle of operation remains the same: the tool makes a hole due to the percussion reciprocating and rotating motion. But the hammer drill is a more powerful and durable tool, and the percussion movements are carried out due to a different mechanism.

In this case, the impact energy works, the mass and inertia of the mechanism itself are taken into account. The power of compressed air works. The piston moves and the compressed air energy is transferred to the ram. It is connected to the striker, which transmits a shock wave to the shaft with the chuck and attachment.
The difference between a hammer drill and a hammer drill is in a smaller amplitude, the tool is much weaker. When working with an impact drill, vibration is transmitted to the hands, the hammer drill has a damper in the form of air, which does not give the hands a load.
This tool is not capable of producing the same precision work as a drill. It is designed for crushing but not drilling holes.

The best hammer drills for the home have clear advantages and additional features among other models in their price category.

Metabo SBE 900 Impuls and Bosh GSB 21-2 RCT. These drills stand out from the high price range. Both models have a reverse function, the ability to adjust the speed and maintain the selected parameter under load.
Bosh GSB1600RE and Makita HP2051F. Good models in the middle price range. The first impact drill is universal, it is distinguished by the build quality and power, it is permissible to use it instead of a construction mixer and for chipping walls. Makita will delight you with a relatively low noise level during operation, lighting and a wide range of materials that you can work with.
Interskol DU-13 / 750T or Bison MASTER DU-810 ERM. These models can be considered among the budget options. In the first case, the build quality and maintainability are attracted, the second model is distinguished by the value for money, good ergonomics and sufficient power.

Cordless impact drill

The main advantages of battery-powered technology are compactness and low weight. It is convenient for working with plasterboard under the ceiling, autonomous and ergonomic. A mains percussion drill with similar parameters will be much heavier and more powerful. There are several points that need attention.

Such a tool is a hybrid of a drill and a screwdriver, it is simple and reliable. Cordless models rarely exceed 410 watts.
Pay attention to the type of battery. For permanent use without long interruptions, a nickel-cadmium battery is acceptable, but it belongs to the short-lived. The metal-hybrid group of batteries is much more reliable, lithium-ion batteries have proven themselves well, but the power will be less, therefore the cordless impact drill-screwdriver will work for only a couple of hours.

Electric Impact Drill

If preference is given to mains-powered technology, three main selection criteria should be taken into account.

The power will be impressive, but this will directly affect the weight and dimensions. The higher the power ratings, the faster the impact drill will cope with the task at hand. Therefore, the scope of work should be outlined in advance in order to select the optimal model.
The choice of hammer drill depends on the desired performance. The rotation coefficient is responsible for this parameter: the higher it is, the greater the performance.
It’s good to know what materials you will have to work with. Torque determines how quickly and easily the drill overcomes rotation resistance.

Impact drill what is it, where it is applied, existing varieties

An impact drill will be an excellent assistant during repairs. It is not designed for constant continuous work, but it will cope with tasks where a conventional hammer drill is powerless. Having set clear tasks, it will be easier to decide on the choice of the model and type of tool.

How is a hammer drill different from a hammer drill?

When the goal is to assemble a cabinet, or to make a hole in any other malleable material, you only need a regular drill. During operation, the drill applies pressure in the direction of drilling and the edges of the drill cut in, deepening layer by layer. Unlike a conventional hammer drill, the device has a slightly different, therefore, works differently.

When the material is solid, it will not be possible to cut anything from it, therefore, additional action must be taken. Reciprocating and rotating movements simultaneously give the same effect. There is a so-called ratchet in the design of the hammer drill: it engages with the stop and vibrational shocks appear along the axis.
The second difference is the principle of influence on the material. The drill does not have a characteristic sharp edge, therefore it cannot cut into the material. This is not necessary. Due to the impact, the structure of the material is broken, and the drill removes the broken pieces.

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, chisel, drill, crown, 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 a 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, skipping over each other. In this case, the chuck and the drill are given an axial reciprocating motion.

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

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

For a hammer drill and a drill, drills and drills are mounted in cartridges, 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 details about the hammer drill chuck, see the article Punch). The fixation in the chuck takes place using specially shaped grooves.

In a hammer drill, the tool has a certain degree of freedom with respect 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 fastening system, the change of chucks is easy and quick, while the chuck for a conventional drill must be included in the hammer drill kit. When using an adapter, a structure 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.

Performance

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

Functionality

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

Tool and fastening

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

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

Working conditions

Criteria for choosing a good tool

The choice in favor of this or that model depends on how you plan to use it. If you need to drill a couple of holes from time to time and periodically screw in the screws, then an impact drill will be enough for you. But if you are moving into a new apartment, or are going to make major repairs in the current one, which involves chipping walls, cutting off jambs, chiselling floors, then it is definitely worth buying a puncher.

If there are hammer drills, why then produce hammer drills?

The impact function of the drill makes it similar to a hammer drill. However, there are still significant differences between them.

How is an impact drill different from a hammer drill? Without going into technical details, we can say that the two instruments have different ways of shaping the blow. As a consequence, for the effective operation of the mechanism, the operator must apply force by pressing on it during the drilling process. But when working with a puncher, the opposite is true. When pressed further, the quality of work decreases and the risk of faster wear of the mechanism increases.

To simplify, the impact function of the drill is additional, and the main hammer. In addition, with the same power and dimensions, the hammer drill will have more weight and cost than the impact version of its “little sister”.

How does an impact drill differ from a hammer drill and which is better for a layman?

The shelves in the kitchen are not screwed on, the mirror in the corridor is not hung, the wife with stubborn methodicalness files you for it, and, as luck would have it, none of your friends has the tool you need for a couple of days. Undoubtedly, there may be other arguments, but there comes a point when you decide that a drill in the house is simply necessary.

If before that you were not the happy owner of such a tool, then at this stage there is a hitch. For the first time, you always want to buy the highest quality item for the most reasonable money. Simply put, make no mistake. And you begin to scrupulously study many models, trying to figure out what will be the best purchase.

To begin with, it’s worth finding out why manufacturers offer a huge range of impact drills, and where all their usual brethren have gone (after all, you think that a drill is a drill, and the percussion attachment means that the model belongs to a different segment). So, the hammer drill is, so to speak, the next generation of our fathers’ tools. This feature has been added by manufacturers to increase functionality. Such tools in our time, so to speak, are put on stream. And therefore, models without a shock function are almost antiques.

What to look for

If you are opting for a hammer drill, here are a few points to look out for when buying a tool:

Power. The larger it is, the easier and more convenient the product is to work with.
The number of revolutions (rotational speed) at idle speed.
The ability to adjust the rotation speed.
The diameter of the holes that the hammer drill creates in various materials in impact mode.
Possibility of reverse movement (movement in both directions). For cases when you need to unscrew the screw or remove the stuck drill from the material.
Number of speeds (one, two or more).
The presence of additional screwdriver bits.

The hammer drill can also be used as a grinder, grinder and stationary drilling machine (fixed motionlessly on the table).

How the impact drill works

In addition to the normal torque, the hammer drill motor also gives the chuck and drill a reciprocating motion. Due to this, the working edge of the drill splits the material at the point of contact, and by means of rotation removes the broken parts and takes them out of the working area.

Drilling is much more efficient, but requires special carbide tipped drills. For example, the victorious ones. They do not have cutting edges in the classical sense, but resemble a chisel firing pin. Only pointed.

Bit soldering on the drill

The device of an impact drill is more complicated than a conventional one. But not enough to radically increase its value. A ratchet wheel is located on the chuck axis. On the body there is a working stop-tooth. When the ratchet is locked (normal drilling mode), only the torque from the gearbox is transmitted to the shaft.

Working in this mode is no different from a conventional electric drill. When the master switches the hammer drill to chiseling mode, the ratchet engages with the stop, and the shaft vibrates along the axis. The gear wheel slides off the stop all the time.

At the same time, the drill literally bites into the material. To reduce wear, the hammer mechanism works only when the drill is pressed in the direction of drilling. When idling, the shaft runs vibration-free.

The principle of operation of the impact mechanism of an electric drill

Due to the constant friction of the ratchet against the stop, the wear of the mechanism is very intensive;
Undamped vibrations gradually destroy the impact drill body;

The rotor and stator of the electric motor also experience parasitic vibrations, which also adversely affects the resource of the tool.

Sharp shaking negatively affects the operator’s hands, increasing fatigue;

From constant work in the drilling-chiseling mode, joints begin to hurt.

The force and amplitude of the reciprocating movements are small, so such a drill is not capable of too strong and hard materials;
Such a mechanism cannot provide chiseling mode without shaft rotation;
Regular maintenance and lubrication of the ratchet is required.

When choosing a home power tool, we are more often guided by emotion than common sense. Mistakenly believing that there is never too much of a good tool, amateur craftsmen purchase bulky and expensive devices for performing simple household chores.

How does each of these tools differ from others?

The purpose of any drilling device is obvious. Punch holes in various materials. Depending on the characteristics of the workpiece, a certain amount of energy is required for drilling. Different types of drills make the operator’s job easier, but there are more advanced ways to improve tool efficiency.

For example, give translational vibrations to the nozzle. Then the drill acts as a chisel or bolt. Over, it is impossible to drill a hole in reinforced concrete in a short time with a classic drill, even with a diamond coating.

How a simple drill works

The electric motor, using a gearbox, transmits the torque to the chuck, and then to the drill. The operator creates pressure in the direction of drilling, the drill with its working edges cuts the material in layers, going deeper into the hole. This rule works when the material is relatively soft and pliable.

So to speak, if there is something to cut. Otherwise, the operator may not be able to move forward. This is the main difference between a conventional drill and a percussion drill. The indisputable advantage is ease of use and the ability to perform work with high precision.

Shockless electric drill with speed switching function

The presence of a speed control adds versatility in terms of drilling various soft and low-melting materials.

What is the difference between a drill and a hammer drill

The hammer drill works on the same principle as the hammer drill, only the chiseling mechanism is implemented differently. In this case, it is the impact energy that is used, taking into account the mass and inertia of the impact mechanism. Effort is realized by means of compressed air as in a jackhammer. The actual jackhammer mode is provided in any rock drill, regardless of size.

In this, the master talks with examples about the main differences between a hammer drill and a drill.

The principle of operation is as follows:
On the shaft with a chuck and a working attachment (chisel or drill) strikes a striker connected to the ram. The ram gets its energy from compressed air, which appears from the operation of the piston. The piston is driven by a crank mechanism or an oscillating bearing.

Schematic representation of the hammer hammer mechanism

The hammer hammer mechanism works with great force and amplitude. Air damper prolongs tool life and protects operator’s hands. At the same time, the work efficiency is an order of magnitude higher than that of an impact drill. Durability is also great.

High complexity (compared to impact drill) and cost;
Bulky mechanism and high power consumption;
Inability to perform more or less accurate work;
The tool is heavy, so it is not easy to work with it for a long time;
Regular lubrication and cleaning of the piston group and attachment holding mechanism.

In this you will find a comprehensive answer to the question: What is the difference between a drill and a hammer drill?
The comparative review addresses the following points:

Visual comparison of rock drill and hammer drill;
Drill and drill fastening (difference in chuck);
Tool power and performance;
Convenience of work.

Which power tool should you choose?

The question is rhetorical. There is no universal tool. Precisely, such copies are available, but no more than to formally fill the consumer niche. The quality of work leaves much to be desired. Therefore, a reasonable choice: each type of work has its own tool.

If you are drilling holes in familiar materials such as metal, wood or plastic, your choice is an ordinary drill. The tool is compact, inexpensive, and not tiring to work with. Power (and, accordingly, size) is not difficult to choose.

If you need to occasionally punch brick walls, buy a hammer drill. The power tool costs a little more, but gives a certain versatility. You turn on the chiseling-drilling mode only when necessary, the rest of the time you work with precision drills and pliable material.

At the same time, the compactness and low power consumption allows the use of the cordless version of the drill. A cordless drill is more like a screwdriver, but we’ll cover that in another article. For a large rock drill (even in the smallest version), the option with a battery is not available.

If you are starting repairs in the house, or building a garage, you cannot do without a punch and this article will help you choose it. Especially if you need a classic jackhammer. In this case, you do not need to send a conventional or percussion drill to the closet. A compact and lightweight power tool is essential for fine finishing.
