Today in the construction markets you can find many various tools, in connection with which, sometimes it is 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 when making holes, niches and openings are perforators 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.
The main purpose of tools
The main difference between a percussion drill and a perforator is their functional purpose:
- for an impact drill. this is the drilling of materials with a low density (wood, plastic, soft metals, etc.). In addition, the shock functions of the drill allow you to drill even concrete and brick. In conventional models, the produced working effect largely depends on the pressure force of the master. Therefore, to obtain the optimal and acceptable impact energy, the pressure force should reach 10-15 kg;
- for a punch. this is chiselling. Impact function is incorporated in the puncher initially, as well as drilling. At the same time, it is not recommended to exert pressure on the punch, as this can lead to tool breakage. The maximum pressure limit should be no more than 5 kg.
Depending on the general functions, using a puncher, you can perform a fairly wide range of work compared to the functionality of an impact drill:
- chipping and driving rods;
- shtroblenie concrete walls;
- drilling surfaces of various kinds, including wood, concrete and steel;
- chips, brick spalls, knocking down tiles, removing plaster and making holes;
- tightening bolts, screws or self-tapping screws
Like any other construction tool, impact drill and hammer drill have a number of distinctive features:
- Shock mechanism
Tools have a different scheme of the mechanism of blows:
- The perforator has an electropneumatic and electromechanical shock mechanism assembly. It produces impact force and provides the most effective operational parameters for this type of construction tool. With the electromechanical type, two coils cause the movement of the core under the influence of electromagnetic effects. The pneumatic mechanism involves the transfer of working energy through a rotating rotor, which drives the piston. Due to the performance of a reciprocating amplitude with a drill, the perforator does not require additional physical loads or efforts, unlike an impact drill;
- The drill has a more simplified design of the percussion mechanism. Often, it consists of two ratchets that connect to a rotating chuck and tool body.
The existing differences in the design of the percussion mechanisms of the drill and perforator determine their different technical and operational standards.
- Modes of Operation (or Functionality)
Modern types of perforators significantly ahead of the drill, because they have full three operating modes:
- single-mode or drilling. the device uses only rotation without impacts;
- three-mode. impacts without rotation (they are also called work in a jackhammer mode);
- dual-mode (rotation with strokes). produce drilling in combination with strokes.

Thanks to these three modes, the punch can be used not only for drilling, but also for other types of work. chipping off excess material, hollowing out strobes or niches in stone walls.
The drill will not be able to provide a high level of speeds, because its shock 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 the presence of additional tools, an impact drill can act as a mixer, grinder, puncher and screwdriver. Conventional. allow you to drill holes in wood and metal products. They also have a subspecies called “angle drills”. they make holes in hard-to-reach places;
- Drill mixers. have an extended extra handle and high torque. Used to prepare a variety of building mixtures;
- percussion. in their design can combine the functions of drilling and impact. With their help, it is possible to drill bricks and concrete;
- screwdrivers. in addition to their main function, they can wrap or unscrew screws.
- The total weight of the power tool
Depending on the weight, perforators are classified as:
- light. the weight of the structure reaches 2-4 kg;
- medium. within 5kg;
- heavy. weight exceeds 5kg.
The average weight of an impact drill can range from 1 kg to 4 kg.
The hammer drill and hammer drill differ in the number of parts used and how they are mounted:
- for drilling in an impact drill, drills with victorious surfacing are most often used. The most vulnerable part in the instrument is ratchets. Therefore, when choosing a drill, it should be borne in mind that under heavy loads and severe vibration, they wear out very quickly;
- in drills, in addition to drills, drills are also used, which are fixed in chucks using a special system of clamps and grooves of a special shape
Having a certain degree of freedom in the movements of the drills in the chuck, the impact load is significantly reduced in the hammer drill.
The possibility of using small or large drills during work depends on the diameter of the chucks.
Unlike a percussion drill, a special adapter is located in the perforator, which allows changing the cartridges if necessary.
Another positive point when choosing a hammer drill is the effect of a lower level of vibration on the hands of the master due to the softening air cushion located in the pneumatic shock mechanism.
It is determined by the value of the impact energy. At the puncher, it ranges from 1.5-20J and is always an order of magnitude higher than that of a percussion drill. This largely depends on the mass of the device and the pressure force of the master. The technical characteristics of perforators can also indicate the frequency of beats per minute: from 4 to 4.5 thousand beats in more powerful models and 2-3 thousand in less powerful ones.
Given the same power of tools, a punch is always much more expensive compared to the price of a hammer drill. However, one should not forget that the punch belongs to the category of professional tools, therefore its cost fully justifies itself. drilling speed and durability in work.
Remember that when working with a hammer drill, you need to apply three times less effort than when using a hammer 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 it is to use the tool in work.
- Availability of rotation speed adjustment.
- Equipped with additional nozzles.
- The number of revolutions idling (rotation speed).
- The volume of speeds (one, two, three, etc.).
- The presence of the possibility of movement (rotation) in both directions (reverse movement). In some cases, this helps to remove the stuck drill.
- The ability to create holes of different diameters in different building materials.
What to choose?
The hammer drill and hammer drill can perform each other’s functions. However, replacing the hammer drill with a drill can cause it to wear out quickly.
The choice of 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 goals for which the construction tool is purchased. If it is necessary to do housework, a functional drill will suffice. For long-term, constant and voluminous work, it is better to use a hammer drill.
- if the work involves the processing of concrete structures or objects from similar materials, it will be preferable to choose a hammer drill;
- The drill is suitable for working with wood or steel products.
