Center drills for CNC machines. Drills are cup and filler. Extra short and short drills
Today, the requirements for the accuracy of 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 at the final stages of 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 of various diameters and depths in products made of metals and their alloys. This tool is designed 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 resistance to abrasion. The products retain the sharpness of the cutting edge for many drilling cycles.
Range of drills for machine tools
This section of the catalog contains several types of drills for CNC machines, sorted into categories. For each type of product, a corresponding marking table is given, which indicates their main parameters and scope. You can purchase drills in the following categories:
- centering;
- ultrashort;
- short;
- long;
- extra long.
Each of the above categories includes CNC drills, which can be selected in a certain range of diameters, as well as depending on the material being processed.
Center drills
This section offers fine carbide drills with sharpening angles from 90 to 120 degrees. Such a tool is used to prepare a tapered groove before drilling a hole of a certain depth. Preliminary processing of the desired point with a center drill improves the positioning accuracy of the main cutting tool. Due 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 machining all common metals and alloys used in modern industry. Depending on the production process, center 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 of 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 choose a tool with a diameter of 1 to 60 millimeters.
Long and extra long drills
This category of drills for CNC machines is used for making through holes in products from 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 the detailed characteristics of each series of tools.

Book title Next page>>4.4. Cutting tools and fixtures for CNC drilling and boring machines. Drills for CNC machines.
Cutting tool. On CNC drilling and boring machines, various types of cutting tools are used: 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 conventional and combined.
Spiral high speed drills may have a cylindrical or tapered 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 tapered shank are produced in ultra-short (GOST 10903-77) and elongated (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 pocket drills most effective when drilling holes with a diameter of more than 25-30 mm. Compared to standard twist drills, they have a number of advantages, the main of which is the lower operating cost per unit of hole length. This is achieved through the use of replaceable cutting blades, which can dramatically reduce the consumption of high speed steel.
Rice. 4.8. The design of the prefabricated feather drill.
Unified prefabricated spade drill(Fig. 4.8) consists of three elements: a replaceable cutting blade knife 1, a holder 2 and a fixing screw 3. Several types of knives are used in such drills: for drilling, for boring and countersinking, for centering and chamfering. The shank is available with internal coolant, cylindrical adjustable shank and 7/24 taper.
Spiral Combination Step Drills used for 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, which reduces the loss of time for auxiliary movements of the working bodies of the machine and tool change. Two types of drills are commercially available - 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 (Fig. 4.10, b). They are subject to high requirements: for example, the runout of the cutting edges relative to the body axis should not exceed 0.02 mm for drills with a diameter of up to 3 mm and 0.03 mm for drills with a diameter of more than 3 mm.
