What types of equipment are there?

Metal drills

Depending on the type of work to be done and the material, one or another type of drill is selected.

Design

• Spiral type

The tool varies in length in the range of 40÷400 mm, and in diameter 1÷50 mm and is considered classic. The same diameter size is maintained along the entire length; along the circumference there is a cutting edge in the form of a screw with a twisted groove for removing the processed material, that is, chips. The cutting element is duplicated into a pair, which is positioned exactly 180°.

Such equipment is suitable for through holes in metals with great depth and for blind recesses. For a specific hole diameter, you should choose a drill rod that is 1 mm smaller in size, since the sides of the material are broken after drilling.

• Step type

The drilling element has a conical design. The edge increases in diameter towards the base and has an intermittent shape. A smooth rise and a sharp edge are present at the beginning of a new step; the drilling process can begin from any of the steps. Each tier has a diameter designation in mm, the number of tiers varies from 5 to 10. Such equipment allows you to make holes of various sizes on one sheet without changing cutting elements, which saves time. An existing hole can be drilled to a wider diameter by starting the process from a certain tier of the drill. Since each tier is included in a single structure, it does not allow for a recess depth of more than 3 mm, which is a significant limitation.

• Crown type

The structure, hollow on the inside of the mold, has many end teeth. The twisted cutting edge continues each tooth and can be in the range of 4÷16. The similarity of the design to a crown determined its name. Using such a drill, you can make large holes with a metal depth of 50 mm. In some cases, an alignment with fixed spiral elements or pins is used to ensure accurate operation.

• countersinks

The conical shape has no steps, the cutting edges are continued with grooves. The countersink is used for small recesses up to 5 mm. In addition to round holes, oval drillings can be made as the diameter increases. You can read more about countersinks here.

• Shank

The strength of the fastening affects the undesirable possibility:

1. center shift;
2. drill breakage;
3. damage to workpiece material.

The type of attachment of the tail section must match the chuck.

• Cylindrical type

The shape of the cylinder follows the design of the cutting edge, but has a smaller diameter to simplify the rotational movement when immersed in metal. Three clamping tabs provide a secure fit when locked in place. A similar type is used in electric drills and small machines.

• Hex type

The hexagonal base smoothly transitions into a cylindrical shape and cutting waves. The type does not require additional fixation by twisting the cartridge and is installed in the receiving coupling of the mating faces. Quick changeover when creating wells of different diameters significantly saves time. All screwdrivers are compatible with hex shanks. Biting of the equipment or reciprocating movements can lead to unwanted falling out of the mounting chuck. This type is not suitable for wells in thick metal.

• Conical type

Reducing the diameter of the tail section at the end allows the element to be fastened with muscle force. The load during operation ensures its firm fit. Removal is carried out with a wedge driven into the slots of the cartridge. The species is widely used in drilling machines. It is allowed to use an intermediate cone with a large diameter of the cartridge.

Preparation method

The parameter determines the strength; lifetime; types of steels to be processed.

• One-piece look

Tooling is obtained by casting and this type is the most common. Made from high-speed steel, these can be countersinks, crowns, spirals and cones.

• Welded type

For hole diameters over 20 mm, welded equipment is used; carbon steel is used to make the shanks. The part has a low cost and a long service life.

• Carbide tips

Alloy BK8 is adapted for elevated drilling temperatures in durable metals. Unilateral sharpening of special technology guarantees an increase in shelf life. It is possible to replace the tip while maintaining the body of the element.

Marking

• H.S.S.

General purpose abbreviation for high-speed steel of high hardness and resistance to fracture, with impurities. Impurities determine the type, properties and cost: P – tungsten alloying; F – presence of vanadium; M – addition of molybdenum.

• HSS-E

Steel with the addition of cobalt from 5% to 8% makes the equipment suitable for working on stainless steel and a strength of 1200 N/mm². Often used in drilling processes in difficult materials with a binding effect when heated. The designation HSS-Co is also allowed.

• HSS-TiAIN

The abbreviation for three-layer coating of titanium, aluminum and nitride marks equipment with heat resistance up to 900°. Work on steel with a strength of 1100 N/mm² is allowed. HSS-TiAIN elements last a long time and outlast other types in service life by 5 times.

• HSS-TiN

Sodium nitride is used as a coating on the outer layer. Thermal resistance characteristics have been increased to a threshold of 600°. A drill with a similar marking is suitable for drilling materials with a strength of 1100 N/mm²:

1. in cast iron;
2. aluminum;
3. alloy steel;
4. carbon steel.

• HSS-G

Grinding with cubic boron nitride makes the cutting part resistant to abrasion and resistance to radial runout. The processed steel is only suitable with a strength of 900 N/mm² and is also used when drilling cast iron materials.

• HSS-R

Elements with conventional heat treatment and roller rolling are used in work on cast iron and mild steels.

Hard alloys

The material is used for tips and is suitable for high temperature loads. The equipment is highly resistant to wear. Can be used when drilling:

1. in titanium alloys;
2. stainless steel;
3. heat-resistant steels.

Center drill

To produce holes in cast iron and steel products, metal and metal-ceramic alloys, combined centering elements are used. Such equipment is considered professional and provides high quality processing and accuracy. An important characteristic is also the elimination of errors and inaccuracies in work. Several surface roughnesses are distinguished in relation to the consumable tool used.

Wood drilling

Construction and repair, manufacturing of parts, many intermediate manipulations in any work require drilling in wood.

Design

The spiral type is common in universal sets that include working on wood, metal, and concrete.

• Forstner type

The twist drill is additionally equipped with cutting elements, and the process produces smooth hole walls and a flat bottom.

Also, the working part can take the form:

1. centering;
2. flat;
3. single-sided for deep drilling.

• Shank

All tail parts can be divided into:

1. cone type;
2. cylindrical;
3. 3,4,6 faceted;
4. SDS.

Drilling in wooden material is specific in that it is enough to choose a drill that is harder in structure than the wood. Common high-strength steel, from which most drills are made, is suitable.

Formwork element

With the help of such a consumable element, a hole is drilled through the inner and outer skins of the boards in one operation. This is due to the length exceeding the usual, average size.

Concrete drilling

For such work, a core, screw and twist drill are used.

Ring elements

The type is necessary for drilling in plastic. You can also use spiral class elements.

Diamond equipment

Feather diamond elements are used for drilling on glass and ceramic tiles. For larger-scale work, such as drilling through reinforced concrete for wiring, there is a special tool and diamond bits for it.

Types of drills

Different types of drilling products are produced, the main difference of which is their purpose.

Spiral . Used for making blind and through holes. The diameter of the working part is uniform, so the product can make holes of only one size. Design differences: cylindrical shape, two helical cutting edges, grooves through which chips are discharged.

Stepped . The product can be identified by its cone-shaped shape, the surface of which is designed in the form of steps. Each of them corresponds to the diameter of the resulting hole. The closer to the shank, the larger the diameter of the cutting element. The peculiarity of the equipment is the ability to make holes of different diameters using one drill. Find out more...

Crowned . The design feature is a hollow cylinder, the lower end of which has serrations. The appearance determines the name of the type of product.

Equipment is used for making holes of large diameters (more than 30 mm). It cannot be fixed to the chuck of a conventional drill or screwdriver.

The throughput capacity of the crown structure is sheet metal up to 10 mm thick. Products can be diamond coated or carbide tipped. The equipment is also suitable for working on concrete.

Feathers . The design is distinguished by a flat shape, at the end of which there is a trident. This solution allows you to make large-diameter holes, while the equipment is easily fixed on the chuck of a conventional drill. When drilling a small groove, a depression from the main tooth remains in the center. You need to work with a feather drill at low speeds. It is often used with a hand crank.

Screw . When making deep holes, it becomes difficult to remove chips. You have to stop drilling and move the working part out to clean the groove. You can speed up the process by using an auger drill.

Its difference from the spiral one is the large angle of inclination of the helical grooves, as well as the increased thickness of the core. The core has the same diameter along the entire length of the equipment, whereas in conventional designs this indicator changes (it thickens closer to the shank).

AEG HSS-G 4932430416

How to choose a drill

Not only the quality of the work performed, but also the possibility of drilling itself depends on the choice. For each material being processed, manufacturers produce equipment that takes into account the density and strength of the surface being processed. Alloys, the shape of the cutting edge and the angle of its sharpening are selected to suit the working conditions. When choosing, it is recommended to take into account not only the type of drill, but also its diameter, length, and shank design features. Our recommendations will help you understand these characteristics; based on them, you can choose a tool that will not let you down when working with any material.

Drill type

Classic spiral models continue to be in good demand. This is a good choice for a home workshop, for solving constantly recurring typical tasks. A simple design, effective removal of dust and chips, and simple installation make this tool convenient to use. Professionals prefer equipment of a more complex shape.

A core drill, which resembles a hollow cylinder in shape, is highly efficient. This tool makes it easy to cut large diameter holes in concrete and steel. Cone drills are distinguished by their stepped shape, each tier has a cutting edge. This allows you to drill holes of different sizes without changing equipment, which has a positive effect on productivity.

To work with wood, spiral models are used that effectively remove chips from the working area. “Ballerinas” help create holes of different diameters, and the feathers have a simple design and low price. Equipment for confirmants, equipped with an adjustable countersink, has been developed for furniture makers. Using a 35 mm Forstner drill, you can easily cut a blind hole for fittings without damaging the façade of the furniture panel or the front side of the workpiece.

Diameter

Diameter is one of the main characteristics. Products are produced with parameters from 1 to 55 mm. An electric drill is rarely equipped with accessories whose diameter is more than 10 mm - the power of the power tool may not be enough to complete the assigned tasks.

When choosing consumables for working with concrete, choose a diameter that matches the size of the dowels used. This allows you to carefully insert hardware into the prepared hole without breaking the shirt. The outer diameter of the dowel will expand after screwing in a screw or driving in an anchor, which will allow the fastener to be securely fixed in the wall.

When making a hole for a thread in metal, take into account the outer diameter of the bolt or screw. This operation has different accuracy requirements. For this reason, manufacturers produce products of different accuracy classes. Products of class B1 and B2 are standard tools, and category A1 are high-precision and are capable of drilling a hole with an accuracy of a fraction of a millimeter.

Length

The length of the drill depends on the type of work the master performs. When drilling sheet metal, no longer is required. This parameter is critical when working with brick, concrete, and wood. During the construction of houses, through holes are needed in the walls for laying utilities. The thickness of interior partitions is from 10 to 40 cm, depending on the level of sound insulation. The parameters of external walls and enclosing structures are from 40 to 60 cm. You can drill a hole using equipment of the appropriate length.

When choosing a tool, it is necessary to take into account that manufacturers indicate the total length in the markings. The working part is noticeably shorter, so it is recommended to check its dimensions when purchasing. For through drilling of concrete, you can purchase drills, the length of the working part of which reaches 90 cm.

Shank type and diameter

What should the shank be like? This part is clamped by a jaw chuck; its shape affects the reliability of the fixation. You can find products with square, cylindrical, triangular and hexagonal shanks. Square shanks have been used since the mid-19th century; they have proven themselves well, but they are difficult to fix in three-jaw chucks.

Cylindrical shanks are the most common. The advantages of this option are simple manufacturing and versatility. At high speeds, such a shank can scroll. This can be considered both an advantage and a disadvantage. Slipping protects against jamming, but does not allow large torque to be transmitted to it.

Hex shanks do not jam at high speeds; the design allows for the transmission of high torque. Work well in combination with jaw chucks. Spiral and feather versions of equipment and Forstner drills are produced with shanks of this type. In the 21st century, tools with SDS shanks, which have a complex shape, have become widespread.

Sharpening angle

The sharpening angle determines productivity, cutting mode and wear resistance. This parameter is selected taking into account the characteristics of the material being processed. For various types of steel, hard bronze and cast iron, the optimal sharpening angle is 116-116 degrees. For softer metals - standard bronze and brass - it is better to choose a cutting edge with an angle of 120-130 degrees. When working with copper, use a tool whose edges are sharpened at an angle of 125 degrees.

Concrete is a less demanding material in terms of sharpening angle. Pobedite tips are sharpened at an angle of 118-130 degrees. To work with plastic, it is recommended to use a tool with a sharpening angle of 90-100 degrees. It is easier to handle wood and aluminum equipment if the angle between the cutting edges is 140 degrees.

5. Metabo Bestell-Nr. 27,094 HSS-G

Metabo Bestell-Nr. 27 094 HSS – G – one of the best drills designed for metal work.

In total, the set contains 25 pieces, the diameter of working tools varies from 1 to 13 mm. The cost of the set is approximately 1,700 rubles.

How to sharpen metal drills correctly

As the cutting edge of the drill becomes dull, it becomes necessary to sharpen it. This can be understood by the following signs: a characteristic squeal, rapid heating of the equipment, longer drilling, decreased accuracy, dullness is felt when touching the edge. To ensure quality work, it is recommended to take into account the following recommendations from experienced craftsmen.

An easy way to sharpen a drill

1. Before sharpening, make sure that the sharpening tool/machine is in good working order and that it is in a stable position.
2. Prepare a container with cold water to cool the metal.
3. When passing the drill along the grinding wheel, you need to press the equipment tightly. Sharpening should begin from the back of the edge.
4. When heating a metal, cool it in prepared water to avoid overheating.
5. The sharpening angle is applied depending on the metal alloy used in the production of the drill.

The entire cutting surface, including the side passages, must be sharpened.

In the catalog you can select equipment both by thickness (1.0...13 mm) and length (3.4...13.3 cm).

DeWALT

Rating: 4.7

The American brand DeWALT failed to wedge itself into the purely German pedestal. The reason for this was the high prices for equipment. The company sells an impressive arsenal of drills on the Russian market; there are models made of tool steel, and there are products made from alloy materials. Experts liked the sharp cutting edge, which makes drilling fast, whether it's wood or steel. The manufacturer boasts a wide range of shanks. Home craftsmen liked the cylindrical designs with 3 edges at the end. They are securely fixed in the chuck and do not rotate in solid material.

Some craftsmen call it a pleasure to work with American equipment. They praise the drills for their excellent quality, but it is better to entrust the sharpening to professional sharpeners.

1. original designs;
2. high quality;
3. rich model range;
4. sharp sharpening.

AEG

Rating: 4.7

The full production cycle at the plant in Germany was organized by AEG. The company's employees develop and manufacture high-quality drills. The experts liked the stone and concrete models the most. They demonstrate enviable performance and wear resistance. Metal drills are just as sharp as them. With their help you can drill holes even in hard grades of steel. But the range of equipment for wood processing leaves much to be desired. The manufacturer also deserves praise for the neat and practical boxes in which the drills are securely fixed in their sockets.

Domestic craftsmen liked the work of small metal drills, with the help of which they can quickly drill out rivets or broken bolts. Flattering reviews are received for products for hammer drills.

Advantages

1. German quality;
2. neat boxes;
3. sharp sharpening;
4. wear resistance.

The manufacturer offers sets for a specific type of material or combined sets, piece products for processing metal, wood, stone, concrete, glass and ceramics. Experts liked the series of drills for glass or ceramics, thanks to the peaked shape of the cutting edge, it creates a neat hole in fragile parts.

Thanks to the presence of alloying additives, equipment is obtained that is capable of processing hard steels, cast iron and non-ferrous metals. There is also a successful series for drilling wood, including Forstner drills. The stores offer different sets and individual products.

Russian users praise SIBRTECH drills for the accuracy of the holes, which does not exceed 0.1 mm from the declared size. At the same time, the high performance is pleasantly surprising. But the choice of shanks is limited only to the cylindrical design.

Advantages

Interskol

Rating: 4.3

There is a high demand for power tools and equipment from Interskol in our country. The manufacturer successfully balances between price and quality, which attracts increased attention from potential buyers. Experts appreciated the presence of a magnetic holder in sets with drills, which securely fixes the equipment in the box. The brand's specialty is the production of drills with a shank for a screwdriver (1/4). The advantage of this design was immediately appreciated by installers working with drywall. When the drill jams, the shank does not rotate in the chuck.

The brand's assets should include a rich assortment of equipment for processing wood and metal, ceramics and glass. But the accuracy of the holes does not always please the craftsmen.

Advantages

1. affordable price;
2. large selection of drills for different purposes;
3. original shanks;
4. good quality.

Flaws

1. There are drills with beating.

Zubr

The range of drills consists of modifications for metal, wood, glass and ceramics. There are even accessories with diamond tips. The manufacturer should include a cross-shaped point as an asset, which facilitates alignment. Many craftsmen also like the accuracy of the holes, which corresponds to the first class. However, the service life of the equipment is short, so the scope of application is limited to household work.

In the reviews, many flattering words are addressed to the Cobalt model (for metal). But the ZUBR 2994-H5 drill set is criticized for its short-lived sharpening. At the same time, all consumers are satisfied with the low price and beautiful packaging.

Advantages

1. low price;
2. variety of models;
3. special sharpening;
4. hole accuracy.

Anchor

Rating: 4.1

There are sets for different types of activities to choose from, as well as individual items. Each product has a marking that encodes the type of steel and the size of the equipment. Experts drew attention to the interesting design of the drills. Deep spiral grooves ensure efficient removal of chips, so the equipment does not get stuck in the material being processed. HSS plays the role of base steel; it does not imply professional use.

Metal drills occupy a central place in the manufacturer's catalog. The range of equipment for processing wood, concrete and glass looks more modest. Standard drills predominate over other types; there are also screw and stepped versions.

For experienced domestic craftsmen, the Ataka company's products in a good sense resemble USSR consumable tools. The drills are difficult to fit; they can be easily straightened. The kits are equipped with a compact plastic box.

Advantages

1. quality steel;
2. sharp sharpening;
3. easy editing;
4. affordable price.

Flaws

1. modest assortment.

Experts especially note the perfect surface grinding, sharp sharpening and laser marking. The company sells most of its drills in sets, among which you can find both specialized and universal ones. The discrete diameter is 0.5 mm, which is enough to perform most tasks in everyday life. The series with a massive body looks the most durable and fracture-resistant.

Russian users praise Inforce drills for their good sharpening, lack of runout, and affordable price. The disadvantages include short-lived packaging and only cylindrical shanks.

Advantages

1. sharp sharpening;
2. drilling accuracy;
3. wear resistance;
4. reasonable price.

Which drill set to buy

When choosing a drilling consumable tool, you must be guided by the following criteria.

Drill type

To carry out work with a certain material. Products can be screw or feather, hollow conical or stepped conical.

Purpose

The user must know what material he will have to work with: glass or concrete, wood or metal. Based on this, choose the appropriate consumables.

Dial type

Store sellers offer customers specialized kits for working with specific materials or universal kits.

Manufacturer

An important factor is also the choice of the manufacturing company. The more reliable the company’s reputation, the longer the working life of their products, the higher the quality of the work performed.

Rules for storing drills

At workplaces of industrial enterprises, drills are stored in tool cabinets and bedside tables made of sheet metal, installed in the immediate vicinity of the machine, as well as on racks in special tool storage rooms. Drilling tools must be placed in a certain order (by type and diameter) in the appropriate compartments, cases or cases. Laying should ensure the safety of cutting edges, as well as working and seating surfaces. Before storing the drilling tool, clean it of metal dust and contaminants, and if not used for a long time, lubricate it with lithol or technical petroleum jelly. In order to prevent corrosion, it is prohibited to place acid-containing or other aggressive liquids near the tool storage areas. In home workshops, tools should be stored in compliance with the same rules. Only instead of bedside tables and cabinets, it is much more convenient to use plastic pencil cases and special stands (see video below).

When drilling deep holes in metal, it is recommended to pour a small amount of oil on the surface of the tool. I-20 is usually used in production, but not everyone has the opportunity to purchase this particular brand. What kind of oil can be used at home instead of industrial oil? Please share your thoughts and recommendations on this issue in the comments.

Criteria for correct selection

For initial orientation in a wide range of proposals, it is important to determine the upcoming scope of work. For home or country use, universal sets with blocks of elements for wood, metal and other materials are more suitable. If necessary, you can purchase additional drills for specific work. Next, select the type of working part, which is described in detail above.

Important things to consider:

• design;
• material of manufacture;
• alloys;
• diameters.

The shank requires the correct approach according to the available tool. You should be guided by:

1. per cartridge;
2. capture;
3. drill removal method.

The cost of all equipment ranges from 9 rubles to 18,000 rubles.

Meaning:

• professional approach;
• specific work;
• required duration of operation.

Errors in selection

An amateur or a professional who constantly deals with tools is bound to face the problem of a shortage of one or another equipment. It is impossible to purchase a set that will meet all needs once and for all. The additional purchase of piece drills can be called a pattern. A specialized process will require universal support. However, having several sets and piece equipment in your arsenal, you can cope with any task. When forming a private workshop, you should not strive to buy a set with the maximum number of units. Also, it is considered unprofitable to purchase expensive instrumental elements in the hope of “someday coming in handy.” It is important to gain experience in drilling, the ability to distinguish between the features of the process and the ability to make the right choice of consumables.
