Drill for a puncher: the choice of a shock-cutting nozzle, its purpose

During the construction or repair of an object, it is often necessary to make holes in a brick, stone or concrete wall. For this purpose, a special electromechanical tool in the form of a punch is used. It is equipped with a working replaceable nozzle that performs rotational and percussive movements. The drill for the perforator is presented in several versions. Therefore, when choosing a product, its design should be taken into account.

What is a drill for a hammer drill: features of a replaceable tool element

The drill is a working shock-cutting replaceable part of an electromechanical tool. In appearance, it looks like a drill bit. For the perforator, the nozzle is made of a more durable material. It is equipped with a tail section with special grooves. It is characterized by a large range of sizes. The drill on concrete has characteristic features in the form of a spiral structure of the department, a peculiar geometry of the edge for carving.

Drill bits for the drill have various shapes and sizes

The drill consists of a landing tail, a spiral rod and a cutting part. By means of the tail end, the element is fixed in the tool holder. The spiral rod is the working part. It is designed to remove dust residues and drilled concrete from the holes. The basis of the element is the cutting part.

The drill is made of several materials. Alloyed tool steel is used to perform the surface. A diamond or graphite solder is additionally applied to the cutting edge. This manufacturing technology allows you to increase the productivity of the product and increase its service life.

Useful advice! To increase the period of operation of the consumable element for the punch, before starting work, the cartridge and the shank must be coated with a special lubricant.

A drill for a puncher is a consumable material for a tool and is used to make holes in a concrete, brick or stone surface. It is impossible to drill metal or wood with such a nozzle. This is due to the specific design of the cutting part. For this purpose, only metal drills for the perforator are used.

Concrete drills are available in various sizes. For domestic use, it is enough to purchase a nozzle with a diameter of 6-10 mm for a small perforator. At the same time, a dowel of the appropriate size is selected. The maximum diameter of the product reaches 50 mm. For fixing large objects, a long drill with a diameter of 20 mm should be used. The length of the product can be 10, 50, 80 and 100 cm. In the manufacture of drills, a strict ratio between diameter and length must be observed to ensure efficient, reliable and durable operation of the nozzle.

Useful advice! Information about the diameter and length of the product is displayed in its marking.

Drill: this is a shock-cutting tool, not a drill

The drill and the drill are similar in appearance. Both variants of consumables are used to make through holes or recesses of a cylindrical configuration. This nozzle is used for plastic, metal and wood.

For dense non-amortized surfaces in the form of concrete, stone or brick, a drill for a perforator is used exclusively. As a result, you can definitely answer the question of how to drill a concrete wall with a conventional drill. In no way, a drill with a drill is used for this.

The main difference between a drill and a drill is the type of surface to be treated

The impact-cutting tool in the form of a drill is much stronger than drills. The dimensions of the drill also exceed the diameter of this type of nozzle. The maximum value of the drill cross section is 14 mm, and this value reaches 55 mm for the drill. The design of the shank is also different. The drill has recesses, and the drill has no grooves. The length of the nozzles is also different. Drills are available in sizes up to 300 mm, and the length of the drill reaches 1 m.

The drill can be used as a nozzle for both percussion and non-impact drills. The drill is not used for this nozzle. The drill is equipped with a head with different edges and several cutting plates. Some models of nozzles are distinguished by a special geometry, thanks to which the tool can be held in the center of the recess. Drills are characterized by low productivity, and the drill can work for a long time in conditions of high impact load.

Classification of impact-cutting nozzles for a perforator

The impact-cutting consumable element of the perforator can be classified depending on the design, which determines the scope of use of the element.

The auger drill is a self-sharpening element, which is mainly used when drilling holes of considerable depth. It is characterized by high strength, endurance, efficiency, the ability to remove crumbs formed in the hole, durability in harsh operating conditions.

Impact-cutting nozzles for a perforator are classified according to their design

A drill in the form of a conventional screw drill is used to create holes of a cylindrical configuration. A pike is used for concrete work. Thanks to its special configuration, it is able to create wide openings. It acts like an electric hammer.

A chisel is used to dismantle materials. A special type of impact-cutting element in the form of a crown is intended for the installation of electrical outlets. With the help of such a drill, a deep hole of the correct rounded configuration is created. It can be safely used when performing strob for laying pipes for water supply.

The wood drill is several times more effective than a similar type of drill. This helps to reduce the working effort, the rapid separation of chips, the preservation of the structure of wood under the action of such a cutter. The earth drill is used to create round holes in the ground, which is carried out due to the special structure of the cutting rod. The concrete drill performs holes in concrete, brick and stone surfaces.

Drill for a concrete drill: types of element

The construction drill is classified according to the design of the spiral part, the type of shank and the shape of the cutting part. Based on the design of the spiral rod, consumable elements for the perforator are screw, spiral and flat.

Flat-type drills are not recommended for use with low-power drills

The auger drill has a large angle of inclination of the spiral groove, which makes it possible to make deep holes. It is also equipped with a self-sharpening tip with a graphite solder. The specific design of the screw spare parts for the perforator contributes to the effective removal of dust and concrete particles from the holes.

The spiral drill has small angles of inclination of the spiral. It is used to create shallow holes. The latter type of tool is characterized by a large angle of inclination of the spiral, which ensures a high speed of drilling holes and effective removal of dust from them. The flat drill is designed for shallow holes. This is the most popular version of the consumable, which is characterized by endurance. It significantly increases the productivity of the punch, while increasing the load on it.

Important! For a low-power drill, it is not recommended to use a flat-type drill.

According to the type of sharpening of the cutting edge, drills on concrete are classic and centering. In the first variant, the carbide plate is represented by a four-sided structure with front and rear faces. Soldering for such sharpening is equipped with one or two cutting edges.

The centering type of nozzle is a modernized version of the classic design. The main advantage of such an element is the absence of the effect of displacement of the drill relative to the initial position.

Drill for a puncher: classification of an element by type of shank

Concrete nozzles can be classified based on the version of the shank. The most popular type is the SDS Plus drill for a hammer drill, which is often used for household and semi-professional tools. It is equipped with a shank with a diameter of 10 mm, which is a cylindrical base with grooves. These recesses are necessary for a reliable connection of the consumable material with the tool.

The nozzle contains 4 slots. Two of them are solid or closed, and the other two are open. The length of the tail section is 40 mm. The diameter of the working edge is in the range of 4-26 mm.

Another type of drill for concrete SDS Max has a tail diameter of 18 mm. Its length is 90 mm. According to the design of the grooves, such a drill is similar to the previous version. The main difference is the difference in the diameters of the working part. For this type, this value starts from 26 mm. This variant of the replaceable nozzle is used for semi-professional tools and jackhammers.

The most popular type of drill for a hammer drill is SDS Plus

An infrequently used option is the nozzle for the SDS Tor perforator. In terms of design, it is something in between the two previous types of products. Its cylindrical part has a diameter of 14 mm. The length of the shank is 70 mm. The diameter of the working part of the nozzle is in the range of 16-26 mm.

The nozzle type SDS Quick in its structure most resembles a drill bit. The tail rod has a hexagonal design. Instead of grooves, it is equipped with veneers or protrusions, thanks to which it is fixed in the punch cartridge. Such a drill of 6 mm (diameter) can be used not only for drills, but also for drills, screwdrivers.

Important! The SDS Quick drill is suitable exclusively for Bosch power tools – for the Uneo and Uneo Maxx models.

The new design of the shank has a drill for concrete Spline. This slotted design was developed by a Chinese company that specializes in the manufacture of perforators. The new generation nozzle is gradually replacing other analogues, proving its effectiveness and reliability.

The SDS Quick drill is only suitable for Bosch perforators

Drills for concrete: types of soldering

There is a special solder made of carbide materials on the cutting part of the drill, thanks to which the effective operation of the nozzle is ensured. In case of its wear, such a product is unsuitable for further operation. Based on the material used for soldering, drills for a concrete drill can be divided into subspecies.

The pobeditovy nozzles are made of an alloy of two high-strength materials in the form of cobalt and tungsten carbide. The first element forms the basis of the product, the second is used as a hardener. Pobeditovy alloy is also widely used for the manufacture of crowns and drills on concrete for drills. The hardness of the material is 80-90 HRA on the Rockwell scale.

Diamond drills are characterized by high strength and durability, which is accompanied by a fairly high cost of products. A diamond is applied to the cutting edge, and not in the form of a single crystal, but by spraying, which is quite enough to increase the strength characteristics of the nozzle without significantly increasing its cost. It is advisable to use such drill bits for drilling reinforced concrete structures, granite and marble. There are also crown modifications of diamond-coated concrete nozzles.

Pobeditovy nozzles have a hardness on the Rockwell scale of 80-90 HRA

The drill can be equipped with a graphite insert, which is formed by immersing the element in a carbide material. This helps to increase the wear resistance, strength and durability of the product, which can make up to 200 holes. You can distinguish such a nozzle by its appearance. It is characterized by a light color of the tip.

Concrete crown: effective solution of repair issues

The principle of operation, the main types of nozzles. Standard sizes of crowns, application features. The resource of the tool.

A budget version of the drill, which is not characterized by durability, is a hot product. In such an element, the tip has a dark color, which indicates additional processing. Durable materials are not used for the manufacture of such nozzles. They are characterized by a low price, wide distribution, since they are performed by underground manufacturers.

Characteristic features of drills for the earth

The nozzle with which wells or holes in the ground are made is called a yamobur. It is widely used in various fields of economic activity, makes holes having a circular cross-section. A drill for the ground on a perforator is necessary when arranging a plot, installing pillars, creating a pile foundation, erecting gazebos or arches, installing fencing, laying engineering communications, building wells or boreholes. The nozzle is made of thick-walled pipe, metal sheet, metal drill, steel disc.

Important! Yamobur can be used with a puncher with a power of at least 850 watts.

The nozzle for the perforator, with which wells are made in the ground, is called a yamobur

The drill for the perforator (for the ground) is presented in two versions, depending on the design of the working part. It can have a spiral shape or be made in the form of a disk hemispherical knife. Experienced craftsmen prefer to use the second option.

There are several types of products: screw, garden and TISE pile drills. The garden nozzle is the simplest mechanical device. It is a two-sided product with a tubular rod, a handle and a milling cutter, which has two blades on the opposite side. Such an earth drill for a perforator is used to create shallow pits or wells.

The auger drill is equipped, in addition to the cutting blades, with a screw auger. Thanks to the detachable design and several milling cutters, a high speed of work is ensured. Increasing the speed of rotation of the nozzle contributes to the deepening of the tool to a certain depth.

The TISE earth drill is equipped with a bearing base and supplemented with some elements. The ground receiver with screw plates and special cutters ensures rapid extraction of soil from the pit. Thanks to the cylindrical drive, it is possible to make a perfectly flat hole in a vertical position. The sliding section of the rod helps to adjust the required depth. If obstacles are found in the ground, a guide pin comes to the rescue.

Yamobury are screw, garden and for piles TISE

The main criteria for choosing a drill for a drill

When choosing a nozzle for household and professional use, different approaches are needed. However, in any case, the drill must be made of a durable carbide material, which contributes to its reliable, efficient and durable operation. You should purchase a set of drills for a drill from a trusted manufacturer that produces high-quality products. Copies at a low price can be used for one-time work. In addition, such products can cause damage to the perforator.

Useful advice! Bosch, Sturm and Makita have proven themselves from the best side.

For domestic use, it is enough to purchase nozzles of the middle price segment, and for professional purposes it is better to choose more expensive copies.

Based on the purpose of the product, the type of shank is selected. The most popular option is the SDS Plus drill, which is used for small and medium-sized capacities. Its diameter is 10-18 mm, the length of the fixed part is 4 cm. To create wide holes, choose the SDS Max nozzle, the diameter of which varies from 18 to 32 mm. The most popular is a drill for a 20 mm hammer drill.

Drills manufactured by Bosch, Sturm and Makita have proven themselves well

If it is necessary to make a hole larger than 32 mm, you should purchase crown drills for the perforator. When choosing a drill, it is also necessary to pay attention to the shape of the cutting part, which can have two, three or four faces. The latter option is the most effective, but has an increased cost.

Important! When choosing a drill by the type of shank, it should be clarified in the instructions for the drill, which version of the nozzle is suitable for it.

Additionally, an extension cord can be purchased for drilling, which increases the length of the hole without changing its diameter. This is very important when performing earthworks and using crowns. The nozzle can be supplemented with a set of rods of different lengths, which expands the functionality of the product, increasing its productivity.

How to use a punch with nozzles correctly

Before using the punch, make sure that there is no damage. If necessary, the tool must be cleaned beforehand. Before inserting the drill bit into the punch, it needs to be lubricated. Otherwise, there may be damage to the rubbing part of the working nozzle when the power tool is heated.

For professional use, it is better to choose drills with a higher price

Then, with some effort, the drill is fixed with a shank in the drill chuck. The occurrence of a click indicates the correct installation of the nozzle. However, for control, you should try to pull the drill back, which should not happen. If there is a backlash, the cartridge must be replaced.

Important! For efficient and long-lasting operation of the power tool, it is required to apply a lubricant for the drill bits before each use of the consumable.

When performing the drilling process, the drill should be removed from the hole every 10-15 seconds. To replace the drill or at the end of the work, it is necessary to press the special ring of the cartridge along the axis in the direction of the power tool, after which you can remove the consumables.

It may happen that the drill cannot be removed from the cartridge. This indicates the deformation of the shank, which occurred during the execution of the work. A similar situation may occur when using a product made of poor quality material. Such a phenomenon can also be observed as a result of excessive exposure to the tool during the drilling operation.

The type of drill should be selected based on the properties of the treated surface

To extract the drill, you can use a vise, where it is clamped. The perforator is pulled out by unwinding movements (from side to side). The cartridge must be in the open position. The stuck drill can be squeezed out using a gas wrench, which will play the role of a lever.

Useful advice! In case of jamming of the replaceable material, the perforator is switched to the impact mode, and the nozzle is removed by twitching on itself.

When the drill is working, the drill can fly out of the cartridge. This is possible as a result of prolonged manipulation of the tool at an angle, a defect in the consumable part or wear of the locking mechanism.

Useful recommendations for using a drill for a hammer drill

The drill must be used strictly for its intended purpose. Conscientious manufacturers indicate information on the scope of use on the packaging, since the nozzles can be equipped with different inserts, profiles and tips.

If the drill does not fit the drill, you can use a special adapter

The type of drill is selected based on the nature of the treated surface. The harder the base, the more rigid the nozzle tip material should be. For a puncher, the best option is a pobeditovy drill or a product made of VK 8 alloy with a high content of tungsten.

The size of the drill on concrete for the perforator is selected not only based on the required hole diameter, but also taking into account the power of the device. The size of the drill for the hammer drill may simply be unsuitable for the tool cartridge.

Useful advice! If it becomes necessary to use a drill that is not suitable for a hammer drill, you can use a special adapter that is used exclusively for professional power tools.

To drill a concrete wall with reinforcement, it is necessary to use a diamond-coated nozzle

When creating holes, follow the recommendations contained in the instructions for the punch. The choice of the optimal speed will depend on the surface material and the type of drill. In the course of work, the drilling axis should not change. This can lead to deformation of the nozzle and its failure.

To drill a concrete surface with reinforcement, you should choose a diamond-coated nozzle. For small holes, a drill for a 6 mm hammer drill with a flat spiral is used.

Having an idea of the features of the drill, its differences from the drill, understanding the types of nozzles, it is easy to make the right choice when buying consumables for a drill that will cope with the task. This is the key to efficient, reliable, safe and durable operation of an electromechanical tool.
