Cutting tool. On drilling and boring machines CNC are used different kinds cutting tool: drills, countersinks, reamers, taps, countersinks, boring bars, etc. Depending on the material of the cutting part, all these tools are divided into high-speed and carbide, depending on the design - into solid and prefabricated, depending on the operations performed - into regular and combined.
Twist HSS Drills may have a cylindrical or conical shank. Spiral high-speed drills with a cylindrical shank are available in short (GOST 4010-77), medium (GOST 10902-77) and long (GOST 886-77). Moreover, all these drills come with a leash and without a leash. Spiral high-speed drills with a conical shank are available in ultra-short (GOST 10903-77) and long (GOST 2092-77). Spiral high-speed drills with a cylindrical shank are designed for drilling holes with a diameter of 1 to 20 mm, and with a conical shank - over 5 mm.
Prefabricated feather drills are most effective when drilling holes with a diameter of over 25-30 mm. Compared to standard twist drills, they have a number of advantages, the main one being lower operating costs per unit length of hole. This is achieved through the use of replaceable cutting plate knives, which can dramatically reduce the consumption of high-speed steel.
Rice. 4.8. Design of a prefabricated feather drill.
Unified prefabricated feather drill(Fig. 4.8) consists of three elements: a replaceable cutting plate knife 1, a holder 2 and a mounting screw 3. In such drills, several types of knives are used: for drilling, for boring and counterbore, for centering and chamfering. Provided various options Shank: with internal coolant supply, with cylindrical adjustable shank and 7/24 taper.
Twist Combination Step Drills used for machining threaded holes. The use of such drills on CNC machines ensures the combination of drilling and reaming, and in some cases the elimination of preliminary centering, thereby reducing the loss of time for auxiliary movements of the working parts of the machine and changing tools. Two types of drills are commercially produced - for drilling holes for threads from M6 to M27 and chamfering (Fig. 4.9, a) and for drilling through holes for threads from M5 to M24 and drilling for screw heads (Fig. 4.9, b).
Rice. 4.9. Types of Twist Combination Step Drills:
a - for drilling holes for threads from M6 to M27 and chamfering; b - for drilling through holes for threads from M5 to M24 and drilling for screw heads.
Centering drills are available in two types: combined (Fig. 4.10, a) and feather drills (Fig. 4.10, b). High demands are placed on them: for example, the runout of the cutting edges relative to the body axis should not exceed 0.02 mm for drill diameter up to 3 mm and 0.03 mm - for drills with a diameter over 3 mm.
Rice. 4.10. Types of centering drills for centering holes:
a - combined; b—feather.
Today's accuracy requirements printed circuit boards have increased significantly. Accordingly, the quality of the holes made should also be higher, and this largely depends on the choice of tools used in production.
Defects often occur when processing printed circuit boards with unreliable drills. Moreover, inaccuracies are noticeable only when final stages production. Therefore, it is very important to use a high quality PCB drill.

The company "IRLEN-ENGINEERING" offers drills for CNC machines used for drilling holes various diameters and depth in products made of metals and their alloys. This tool intended for industrial use in metalworking industries. Drills for machine tools are made from high-quality raw materials with the addition of special components that increase their strength and abrasion resistance. Products remain sharp cutting edge over many drilling cycles.
Assortment of drills for machine tools
This section of the catalog contains several types of drills for CNC machines, sorted by category. For each type of product, a corresponding labeling table is provided, which indicates their main parameters and scope of application. You can purchase drills from the following categories:
- centering;
- ultra-short;
- short;
- long;
- extra long.
Each of the above categories includes drills for CNC machines, which can be selected in a certain range of diameters, as well as depending on the material being processed.
Center drills
This section offers drills made from fine-grained hard alloy with sharpening angles from 90 to 120 degrees. This tool is used to prepare a cone-shaped groove before drilling a hole of a certain depth. Pre-processing the desired point with a centering drill allows you to increase the positioning accuracy of the main cutting tool. Thanks to this, a longer drill will pass into the metal along the desired axis, without deviating from the calculated entry point due to vibrations and other factors.
The centering tool in the catalog is universal and suitable for processing all common metals and alloys used in modern industry. Depending on the production process Centering drills for CNC machines can be purchased with a diameter of 1 to 30 millimeters.
Extra short and short drills
Ultra-short drills for metalworking are tools up to three diameters long. The catalog contains tools for processing steel, non-ferrous metals and various alloys. Depending on the series, these drills are offered with a diameter from 1 to 20 millimeters. The tool is mainly used for drilling blind holes for subsequent threading for fasteners.
Short metal drills for machine tools can be used for drilling blind as well as through holes in workpieces of small thickness. The length range of short drills is from three to eight diameters. Depending on the material being processed, you can select a tool with a diameter from 1 to 60 millimeters.
Long and extra long drills
This category of drills for CNC machines is used for making through holes in products made of various metals and their alloys. Long and extra long drills are available in diameters from 1 to 30 millimeters and lengths from 8 to 30D. In the catalog you can find detailed characteristics each series of instruments.
