What To Make From Drills From A Punch

Nozzles on the punch, such as drills, chisels, crowns, peaks, blades are designed to perform a variety of jobs: chipping, drilling, chiselling. Thanks to their use, the functionality of the device has greatly expanded. Due to the impact function and high-strength, wear-resistant replacement parts, the tool can work with hard materials. Each type of perforator nozzle is characterized by its design features and sizes. In addition to the main types offered by retail chains, there are a number of modifications created by masters at home.

Drill classification

The most widespread among all replaceable nozzles for the puncher is the drill. The rest are applied in practice less often. Drills in their design consist of the following parts:

  • Tail (shank);
  • Working (with a tip).

With their help, during construction, electrical installation and other types of work, holes are made in concrete, brick, cinder block, stone, wood, metal and other materials. A general view of the product is shown in the photo below.

Types of Tail Parts

The shank is characterized by a high degree of resistance to wear and serves to fix the drill in a perforated cartridge. It is made from high strength steel grades. Allocate such types of shanks:

Designated Products Sds plus. This is the most common variety of the tail parts (c d = 10 mm and L = 40 mm) for drills with a diameter range of 4 ÷ 26 mm. Such a shank has four grooves (open type) designed to fix in the cartridge. It is suitable for small punchers (domestic or construction).

For tips with d 16 ÷ 40 mm (mostly over 2.6 cm) and a total length of 0.25, 0.45, 0.55, 0.8, 1.2 m, which are used in heavy perforators with relatively high power, or chippers with an electric motor, tail parts are used Sds max. For such a shank, the diameter of the section inserted into the cartridge is 18 mm, and L = 90 mm.

Marked tail Sds quick Designed primarily for use with Bosch rotary hammers. She has a holder and dowels. This allows you to use bits from a screwdriver, as well as drills.

Sds top in practice, it is used and found much less frequently than the other types of shanks for drill bits with a diameter range of 1.6-2.6 cm. The length of its tail section fixed in the cartridge is 70 mm, and d = 14 mm.

The type of liner determines the possible sizes of the drill.

Varieties of working parts and tips

Manufacturers make the working part of various shapes using special hard alloys. They determine the safety of using the tool and affect the speed of work.

According to their purpose, the Boers are divided into the following varieties, depending on the shape of their working part:

  • Auger, designed for drilling holes of different diameters and depths in various materials, ensuring effective dust removal and thereby reducing the load on the tool;
  • Having a small angle of inclination of the grooves, which are used when drilling holes of small depth;
  • With a large angle of inclination of the grooves, designed for high-performance drilling at high speeds of a small number of deep holes, but the working load on the tool used increases.

Due to the presence of grooves, centering is provided, as well as the stability of the drills when drilling holes, vibration is reduced. This reduces the load on the working tool.

Using a long drill, it should be borne in mind that it is more difficult to work with it than a short one. It is necessary to constantly observe safety precautions.

The tip is a cutting element of the drill, which is a solder made of hard alloys.. Its quality determines to a large extent the life of the nozzle, as well as the quality and speed of work. Tips in the form that soldering has are divided into such varieties:

  • Classic (cross-shaped soldering);
  • Centering (with a special form of soldering).

There are also wave-shaped cutting edges.

Tips are diamond and victorious. Via diamond tips it is possible to work on reinforced concrete and stone. They have very high wear resistance and durability.

Winning Soldering by strength are divided into the following types:

  • Soft, used for drilling on brick and low-quality concrete;
  • Medium strength, suitable in domestic conditions;
  • High strength, almost similar to diamond.

Drills for concrete or other material at a cost are divided into cheap, domestic and professional. The latter have the highest price, but they are allowed to be used even for drilling reinforced concrete.

The difference between drill and drill

The drill and punch drill are almost identical to each other. But they have the following differences.

  1. Different tail parts: they are smooth in drills, and in drill bits of complex shape.
  2. The edges of the spirals at the drill are designed to be inserted into the material being processed, and at the drill they provide the removal of dust particles during operation.
  3. Different strength: the Boers have it higher.
  4. Drills are suitable for both drill and perforator (when using special adapters), and drills. Only for the last tool.

Drills are designed to work in rotational mode, and drills. In shock-rotational, so when drilling on metal and wood used first.

What are crowns for?

The drill bit is an indispensable nozzle during electrical work: drilling walls for junction boxes, built-in switches and sockets. It is a shank with a cylinder fixed on it, equipped with victorious teeth or diamond spraying.

The table below contains varieties of crowns according to various criteria.

There are models with a steel cutting edge and tungsten carbide.

Diamond crowns allow you to perform work on reinforced concrete and concrete, but are expensive. They have a diameter of 25 to 130 mm and are used mainly by professionals.

Winning crowns lower cost, but they do not take reinforced walls. Their diameter is from 35 to 120 mm.

Impact nozzles Designed to be used when operating a rotary hammer in rotary hammer mode. With their help, hard materials are drilled, not reinforced walls or ceilings. At shockless drilling method Diamond crowns are often used.

Sds-plus core bits are used for small power drills, and SDS-max are used in larger tool sizes. These tail parts are mainly intended for carbide crowns. Diamond nozzles are used more often on drilling machines.

“Dry” and “wet” cooling methods are designed for perforators of various types and nozzles of various diameters. The requirements for the operation of crowns set out in the operating instructions for them should be observed. This will maximize the life of the nozzle.

A number of models of crown nozzles has a drill located strictly in the center, extending beyond the working plane. This design feature helps to accurately carry out drilling along the marking. The central drill acts as a guide.

The type of the tail should correspond to the hammer used in the work, otherwise you will need to use a special adapter. The crown must necessarily correspond to the material of the wall, so as not to quickly fail. Drilling deep holes requires the use of extension cords. In everyday life, nozzles are most often cooled by air.

Chisels, spades and shoulder blades

When working with a puncher, you often have to use a chisel, lance and spatula. These nozzles are shown in the photo below.

Chisel intended for chiselling concrete. The end is not hardened, therefore, it requires periodic sharpening. Often, using this nozzle, they remove old tiles and plaster. To extend the recesses under the cable, a channel chisel is used. The width of the working edge of the nozzle is different (a typical version is 20 mm), and the length reaches 250 mm.

To punch a hole in the walls of brick or concrete with a punch, a peak is placed on it. It can also be done groove for strobes for electrical wiring. The holes obtained when working with the lance require further processing, because it is difficult to make them accurately.

For shtrobleniya walls, floors, ceilings for laying wiring used a spatula with a semicircular shape. She acts as a cheap alternative to a chisel cutter.

When choosing nozzles, their dimensions (lengths, diameters) are primarily taken into account, which should contribute to the performance of the required work with maximum efficiency. The quality of products also holds a leading position, because professional replacement parts become unusable for a very long period, even with heavy use. Despite their high price, they are recommended by specialists for regular use in work. This increases not only the tool life, but also the speed of the work, as well as their quality.
