Bur for the punch: the choice of shock-cutting attachment, its purpose

During the execution of works on the construction or repair of objects often have to make holes in brick, stone or concrete wall. To do this, use a special tool in the form of electromechanical punch. It is equipped with a replaceable working attachment which provides rotational movement and percussion. Bourg for perforating presented in several embodiments. Therefore, when choosing products should take into account its design concept.

What is to drill perforator: features replaceable tool element

Bur is a working shock replaceable cutting part electromechanical tool. In appearance it is similar to the drill. For gun nozzle is made of a more durable material. It is equipped with a tail part with special grooves. It characterized by a large range of sizes. Bur concrete has characteristic features in the form of helical structure department peculiar geometry for threading edge.

Bur tail consists of planting, the spiral rod and a cutting portion. Through tail closure element is fixed in the tool holder. The spiral rod is a working part. It is designed to remove dust and residues from concrete drilled holes. The basis element - the cutting unit.

Boer is made of several materials. To perform surface alloyed tool steel used. The cutting edge is further applied to soldering of diamond or pobedita. This manufacturing technique allows to increase product performance and prolong its service life.

Useful advice! To increase the period of operation of a supply element for the gun, before starting work chuck and shank is necessary to cover the special grease.

Bourg for perforating a consumable product for the tool and is used for making holes in concrete, brick or stone surface. Drilling metal or a nozzle can not be a tree. This is due to the specific design of the cutting portion. For this purpose, only to drill for metal punch.

Drills for the concrete are available in different sizes. For residential use for a small punch is enough to get the nozzle diameter of 6-10 mm. When this plug is selected of the appropriate size. The maximum diameter of the product reaches 50 mm. you should use a long drill diameter of 20 mm for attaching large objects. Product length can be 10, 50, 80 and 100 cm. In the manufacture of drills should be observed strictly ratio between the diameter and length to provide efficient, reliable and durable attachment work.

Useful advice! Information on the diameter and length of the product is displayed in its labeling.

Bourg: This shock-cutting tool, not a drill

Drill and drill bit similar to each other by their appearance. Both variants of consumables used to perform the through-holes or recesses of a cylindrical configuration. This nozzle is used for plastic, metal and wood.

For dense non-depreciable surfaces in the form of concrete, stone or brick is used exclusively for a drill perforator. As a result, you can clearly answer the question of how to drill a concrete wall of a conventional drill. No way, this is used to drill hammer.

Shock-cutting tool as the drill is much stronger drills. The dimensions of the drill is also superior to the diameter of the nozzle type. The maximum value of the cross section of the drill is 14 mm, and a drill, this quantity reaches 55 mm. It is also characterized by design of the shank. In the drill, there are recesses and grooves in the drill no. The length of the nozzle is also different. Drills are available up to 300 mm and drill length is 1 m.

Bur can be used as a nozzle for the drum, and for perforating unstressed. Drill is not applicable for this tip. Drill head equipped with various edges and more cutting inserts. Some models feature a special nozzle geometry, whereby the tool can be held in the center of the recess. Characterized by low productivity drill and drill can operate for a long time under conditions of high shock loads.

Classification of shock-cutting nozzles for punch

Shock-cutting punch consumable element can be classified, depending upon the design that defines the scope of use of the element.

Auger element is self-sharpening, which is mainly used when drilling holes of considerable depth. It is characterized by high strength, endurance, performance, the ability to output the resulting hole in the crumb, durability under conditions of severe operation.

Bur in the form of a conventional drill screw is used to create a cylindrical configuration holes. For work on concrete used peak. Thanks to its special configuration, it is able to create a wide opening. It acts on the electric hammer type.

To disassemble the materials used chisel. To install electrical outlets is a special type of shock-cutting element in the form of a crown. With such a deep hole drill is created correctly rounded configuration. It can be safely used in the performance of cutting grooves for laying pipes for water supply.

Boer wood on the effectiveness of several times the same type of drill. This helps to reduce the operating forces, the rapid separation of the chips, wood preservation structure under the action of the cutter. Earth drill is used to create circular holes in the ground that is carried out thanks to the special structure of the cutter bar. Drill holes in concrete performs in concrete, brick and stone surfaces.

Bur for the gun on the concrete: the element species

Building drill classified by structure of the scroll portion, the type and form of the shank of the cutting part. Based on the structural performance of the spiral rod, expendable perforating elements are screw, and a spiral by rolling.

Auger has a large helix angle grooves, which provides the ability to perform deep holes. It is also equipped with self-sharpening tip with pobeditovye soldering. The specific design of screw parts for the gun contributes to the efficient removal of dust from the holes and concrete particles.

Spiral drill has a small helix angles of inclination. It is used to create a shallow holes. The latter type of tool features a large angle of inclination of the helix, thereby providing high speed drilling holes and effective removal of dust from them. Gentle drill for shallow holes. This is the running version of consumables, which is characterized by endurance. He significantly increases the productivity of the gun at the same time increasing the burden on him.

Important! For low power perforator drill is not suitable for use gentle type.

By type of sharpening the cutting edge of drills for concrete are classic and centering. The first embodiment is represented carbide plate tetrahedral structure having front and rear faces. Soldering for such optimizations are equipped with one or two cutting edges.

Centering type nozzle is modernized version of the classical design. The main advantage of such an element is the lack of effect of the displacement of the drill relative to the initial position.

Bur for the punch: the classification of the element of the shank type

Nozzles for concrete can be classified based on the embodiment of the liner performance. The most popular type is the drill for SDS Rlus punch that is often used for domestic and semi-professional tool. It features a shank diameter of 10 mm, which is a cylindrical base with the notches. These grooves are needed to connect the consumable material on the tool.

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

Another type of drill for concrete SDS MAX tail portion has a diameter of 18 mm. Its length is 90 mm. By such a structure of grooves drill similar to the previous embodiment. The main difference is the difference in diameters of the working part. For this type starts from the value 26 mm. This embodiment uses a replaceable nozzle for semi tool and hammers.

Infrequently used is one gun nozzle SDS Top. By design it is something in between the two previous types of products. Its cylindrical portion 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 16-26 mm.

Nozzle type SDS Quick in their structure is more reminiscent of a drill. Caudal rod has a hexagonal structure. Instead of grooves it is equipped with veneers or projections through which the punch is fixed in the cartridge. Such a drill (6 mm diameter) can be used not only for rotary hammers, but also for drills, screwdrivers.

Important! Boer SDS Quick suitable only for power tools from Bosch - for Uneo and Uneo Maxx models.

The new design of the shank has a drill for concrete Spline. Such a slotted design is developed by a Chinese company that specializes in the manufacture of rotary hammers. new generation nozzle is gradually replacing other counterparts, proving its efficiency and reliability.

Drills for the concrete: species solders

On the cutting part of the drill has a special soldering of the carbide material, which is essential for effective operation of the nozzle. In case of wear such a product is unsuitable for further use. Based on the material that is used for soldering, drills on hammer for concrete can be divided into subtypes.

Pobeditovye nozzle made of an alloy of two materials of high strength in the form of cobalt and tungsten carbide. The first element is the basis of the product, the second is used as a hardener. Pobeditovye alloy is also widely used for the manufacture of crowns and drills to drill concrete. The hardness of HRC 80-90 HRA.

High strength and durability are characterized by diamond drills, which is accompanied by rather high value products. In diamond cutting edge is applied, and not in the form of a solid crystal, and by sputtering, then is sufficient to enhance the strength characteristics of the nozzle without significantly increasing its value. These tips for perforating (drills) should be used for the drilling of reinforced concrete structures, granite and marble. There are also crown modification tips for concrete Diamond Products.

Bur pobeditovye can be equipped with an insert which is formed by immersing the element in a carbide material. This enhances the wear resistance, strength and durability of the product, which can perform up to 200 holes. Distinguish such attachment can be in appearance. It is characterized by a light color nozzle.

Budget for this drill, which is not characteristic of durability, the product is tempered. Such a tip element has a dark color, indicating that additional processing. strong materials are used for the manufacture of such nozzles. They are low cost, widespread, as are performed underground producers.

Characteristic features of the Boers for land

Nozzle, by means of which performed well or hole in the ground, called the anchor truck. It is widely used in different spheres of economic activity, making holes having a circular cross section. Bur to land on the drill is required in the regeneration section, installing the pillars, creating a pile foundation, construction of arbors or arches, installing fences, in laying of utilities, construction of wells or wells. The nozzle is made of a thick-walled pipe, the metal plate, drills for metal, steel disk.

Important! Anchor truck may be used to perforate input of at least 850 watts.

Bourg for perforator (to ground) is presented in two versions depending on the working part of the structure. It may have a spiral shape or be formed as a hemispherical disk knife. Skilled craftsmen prefer to use the second option.

There are several types of products: worm, garden and drills for TISE piles. Gardening tip is a simple mechanical device. It is a two-sided product barbell tubular execution, the handle and cutter, which has two opposite side blades. Such an earth drill to punch used to create shallow pits or wells.

Auger is equipped, in addition to the cutting blades, screw auger. Due to the split design, and several mills provides high speed. Increasing the nozzle speed contributes burial tool to a predetermined depth.

Bourg for land TISE equipped with base plate and added some elements. Sample receiver with screw plates and special cutters ensures rapid extraction of soil from the hole. Due to the cylindrical drive can perform a perfectly smooth hole in the upright position. Spreading section bar facilitates adjusting the desired depth. In the case of detection in the ground to help the guide pin comes obstacles.

The main criteria for the selection of the drill to punch

When selecting nozzles for household go professional use requires different approaches. However, in any case, the drill must be made of durable carbide material, which contributes to its reliable, efficient and durable operation. You should buy a set of drills to punch a trusted manufacturer that produces high quality products. Copies at a low price can be used for a single operation. In addition, these products can cause damage to the punch.

Useful advice! With the best hand proved to be the Bosch, Sturm and Makita.

For domestic use is enough to get the nozzle middle segment, and for professional purposes it is better to choose a more expensive items.

Based on the purpose of the product, selects the type of performance of the shank. The most popular option is to drill SDS Rlus, which is used for small and medium capacities. Its diameter is 10-18 mm, the length of the fixed parts - 4 cm. To create a wide openings should be selected nozzle SDS MAX, the diameter of which varies from 18 to 32 mm. The most popular is a drill for perforating gun 20 mm.

If you want to perform an opening larger than 32 mm, it is necessary to acquire core bits on the punch. When you select a drill is also necessary to pay attention to the shape of the cutting part, which may have two, three or four sides. The last option is the most effective, but has a higher cost.

Important! When you select a drill shank of the type should be specified in the manual for the gun, which option is suitable for packing it.

Further drilling can be purchased extension, which increases the length of the aperture without changing its diameter. This is very important when the excavation and use of crowns. The nozzle can be complemented by a set of rods of different lengths, that extends the functionality of the product, increasing its performance.

How to use a hammer with attachments

Before using the gun to be sure there is no damage. If necessary, the tool requires a pre-cleaned. Before inserting the drill bit into the hammer, it is necessary to lubricate. Otherwise, there may be damage to the friction of the work nozzle by heating the tool.

Then drill with some effort shank is fixed in the cartridge to the gun. Occurrence click indicates proper installation tips. However, to control should try to pull the drill back, what should not be done. If there is a gap, it is necessary to replace the cartridge.

Important! For efficient and durable operation power required to apply the lubricant for drilling perforator before each use of consumables.

When the drilling process every 10-15 seconds drill must be removed from the hole. To replace the drill or the end of work necessary to press the special ring holder axially towards the tool, whereupon the material can be removed consumable.

It may happen that the drill will not be able to get out of the cartridge. This indicates liner deformation, which occurred during the execution of the work. This situation may occur when using the article made of a material of poor quality. This phenomenon can also be observed as a result of excessive exposure to the instrument when performing a drilling operation.

To extract the drill can be used vise, where it is clamped. Perforator pulled unwinds movements (side to side). The cartridge in this case must be in the open position. Stuck drill can be overcome by using pipe wrench, which will act as a lever.

Useful advice! In case of jamming of the replaceable material is transferred to a pin punch mode, and the nozzle is collected by the jerking.

When the perforating drill can fly out of the cartridge. This may result in longer tool manipulation obliquely, the defect portion of the flow or wear of the locking mechanism.

Useful tips for using a drill to punch

Bur should be used exactly as prescribed. Conscientious manufacturers indicate on the packaging information on the field of use, since the nozzle can be fitted with different inserts, profiles and tips.

Type drill is selected based on the nature of the machined surface. The harder the base, the more rigid material to be nozzle tip. For best one perforator is pobeditovye drill or article alloy VC 8 having high tungsten content.

Concrete drill size is selected for the punch not only according to the required hole diameter, but also with the power unit. The size of the drill to punch may simply not be suitable for the tool holder.

Useful advice! If you need to use a drill bit that is not appropriate for the gun, it is possible use the special adapter, which is used exclusively for professional power.

When creating holes should be guided by the recommendations contained in the instructions to the punch. Selecting the optimum speed will depend on the material surface and the type of drill. In the process of work drilling axis must not change. This can lead to deformation nozzles and its exit from the system.

For drilling concrete surface with the reinforcement should be selected with diamond-tipped nozzle. For small drill holes used for punch of 6 mm with a flat spiral.

Having an idea about the features of the drill, it differs from the drill bit, figuring tips, easy to species make the right choice when buying consumables for the gun, which cope with the task. This is the key to effective, reliable, safe and durable operation of the electromechanical tool.
