Drilling or boring. an experienced specialist involved in finishing, repair and construction works will answer this question very easily. It’s all about the scale of the task. A puncher is an electromechanical tool in which a consumable exchangeable part performs rotational and shock movements. The mode is selected depending on the purpose, the main purpose is to create holes. It can be used for interior decoration or as a simple jackhammer punching various designs.
The difference from the impact drill consists in the pneumatic principle and a more powerful electric motor, which creates much greater production capabilities while reducing working time. The drill is a working shock cutting interchangeable part.
Drill for a punch. this is not a drill, although in appearance they are very similar. The principal differences of the first: tail end, more durable material, a larger range of sizes. The shank is the part that fixes and fastens firmly in the drill chuck. For drills, such a device is not provided. The construction classic claims that a drill is a consumable that is no longer improving. Perhaps that is why the sale is carried out as part of sets "for all occasions."
In order for the tool to serve well and for a long time under severe operating conditions, the use of special grease is necessary. It is applied prior to use both on the perforator cartridge and on the shank of the replaceable part.
Boers are of various types. Instances for working on metal are not very effective for use on the ground, a good option for wood is not too suitable for working on tiles. As a different criterion, there can be not only the quality of the metal or alloy, but also the design features. Shnekovy is a self-sharpening "worm variant" used when working at a large drilling depth. It removes the resulting crumb well, is "hardy", more durable in conditions of harsh operation.
It is customary to classify impact cutting tools into several types.
- Like an ordinary drill. well applicable for creating cylindrical holes.
- Peak. used in concrete operations. Serves as an "electric hammer" to form wide openings.
- Chisel. suitable for materials that need to be dismantled. For example, when dismantling tiles or old plaster.
- Crown. this type is used to solve specific problems, for example, in preparation for the installation of electrical outlets. Appointment. creation of deep holes of the correct form. Creating wide openings for laying water pipes is another typical application.
- Wood use superior in efficiency to the use of similar drills at times. Reduced work effort, chips are separated faster, the structure of the tree under such a cutter is not destroyed.
- Earth and construction drill. These are various production topics for a similar design. The first is applicable not only with the engine, but also in the manual version, with the drive of human muscular strength, since it does not require a large intensity of rotation.
Length and diameter are also important differences. For purely homework, products with diameters in the range from 6 to 10 millimeters are applicable. The dowel must strictly comply. Prerequisites for securing fasteners for large objects are a long drill and a diameter of 20 mm. The maximum cross-sectional diameter can reach 5 centimeters. The length of the product is 10, 50, 80, or even 100 centimeters, depending on the thickness of the material being pierced.
An idea of the capabilities of the sample is given by the marking that is applied by any self-respecting manufacturer. For example, a combination of numbers 6.5×160 indicates a diameter of 6.5 mm and a length of 160 mm. Other dimensional options. similarly. The manufacturer combines the length with the diameter so that the tool works efficiently and long-term.
The set of criteria for choosing a household or industrial product is very diverse. The basic requirement is a confident solution to the problem of overcoming the hardness of the material. The second question is the choice of the optimal solution based on price and quality. Here, as in other market cases, one must be wary of fakes and not expect miracles from specimens in the low price category. A good supplier naturally appreciates himself, but this does not mean that he is not faked. A cheap copy can be a tool only for one-time work.

The credibility or at least the fame of the manufacturer is the rule for choice. It is important that during further operation, the hammer is not damaged. There are such products that, in general, should not be inserted into the cartridge. It’s better not to chase the lowest price too and be safe.
Manufacturers such as Makita, Sturm or Bosch are among the most sought after. They do not need special recommendations, but you should pay attention to manufacturers of the same company. Unfortunately, products of the same brand, produced in different countries, can vary in efficiency and durability.
The most expensive segment is intended for professionals, for home use labeled parts in the middle price category are quite suitable. The quality of the material determines the range and potential resource of application. When choosing a target for purchase, it is necessary to take into account the design of the tail section, which is fixed.
Shanks are usually divided into different types according to a special fixing system. SDS and SDSplus are most in demand for medium and small capacities with a diameter of impact cutting tools of 10-18 millimeters, the length of the fixed part is 4 centimeters. SDStop is used when the drill diameter is 14 millimeters.
SDSmax is used for more powerful devices, the mounting depth here is 9 centimeters, and the diameter is from 18 millimeters. SDSquick. Bosch’s development for the “tail” in a hexagonal section, provides a tight and reliable mount in conditions of increased load and vibration. When choosing consumables by the type of shank, it is first of all necessary to look into the manual of the drill. The manufacturer, as a rule, accurately indicates this parameter.
In some cases, an extension cord is required to solve the production problem. It increases the length of drilling without changing the diameter of the hole. It is very important when using crowns or in the process of excavation. One desired specimen can be supplemented by a set of rods of various lengths, which increases production capabilities. For example, specialists making a well in the ground using a gasoline or electric motor can thus go deep to one and a half to two meters.
How to use?
Before starting operation, always check for damage and clean the tool if necessary. After that, lubricate the rubbing parts, then with some effort insert the drill with the shank into the cartridge. A click can be considered a signal of the correct action. A control attempt to unsuccessfully pull the drill back is for insurance.
After completing work or to replace the drill, press the chuck ring in the direction of the tool along the axis, after which we can expect the extraction to succeed. Unfortunately, in practice there are times when this does not happen. This is typical if the shank was deformed during operation. One possible reason is the low quality of the metal under excessive pressure during the operation. Lack of lubrication provokes this matter even more, because the tool heats up.
Practitioners suggest using a vice where the drill is clamped, and the punch is pulled out from side to side. The cartridge is in a strictly open position. Be that as it may. consumables are no longer suitable. If this does not help, a punch should be clamped in a vice using gaskets to prevent damage to the case. A stuck drill is also crimped with a gas wrench that acts as a lever. A few hammer blows on the key will show how vain the hopes are. If success is not achieved, you will definitely have to disassemble the hammer, for which it is better to contact a regular service center.
If the tool is stuck directly in the structure, switch to impact mode. Further, by pulling with twitching on yourself, you can try to achieve success by sorting out the cause of jamming. The worst option is when the stuck consumable item is simply cut off with an angle grinder.
Sometimes the user is faced with a different kind of trouble. the drill flies out of the cartridge. The phenomenon does not allow to conduct quality work and threatens safety. The reason may be prolonged work at an angle, defective consumables or wear of the locking mechanism. If it is not a matter of the storm and the conditions of its use, the repair of the punch can be assessed as a sudden task. Is it possible to sharpen a drill? This is constantly being discussed by beginners.
Sharpening is fundamentally possible, but the effectiveness of this work is very controversial:
- need an appropriate industrial tool for the operation;
- need an experienced master.
Before making a decision, the user must evaluate how much such work will cost in comparison with the price of a new product. In industrial options at construction sites, drills are simply replaced because the developer considers the benefits.
A quickly broken specimen is very disappointing, so it should only be used in acceptable ranges of capabilities. Basic requirement: the harder the drilling material, the harder the tip material. Experts recommend using Win or VK8 alloy. a technology with a high tungsten content. Screw constructions, as a rule, "live" longer. Do not force the drill into the drill chuck forcibly; nothing good will come of it. This option is perfect for a different design and power.
It is generally accepted that the stronger the spiral is twisted, the higher the rotation speed should be. A deeper hole is obtained in the same time. In any case, the recommended operating speeds should be used. The drilling axis should not be changed during the process, as this creates a potential risk of deformation.
In the event that you have to drill on concrete with reinforcement, the tip should be diamond-coated or consist of such an alloy for which, that concrete, that metal. is nothing. No matter how the circumstances evolve in the course of the task, you should never forget about security measures. The future success or failure of the operation always begins with this. Small holes are made with products where the spiral is more than a canopy. In general, before starting, you need to clearly understand what kind of tool will be required. Excessive efforts do not improve the quality of the workflow. Any deformation makes the device unsuitable for use, including safety requirements.
