Countersink set with uneven cutting edge pitch, 6 pcs. HSS Al-Cro, DIN 335, form C 90° BOHRCRAFT.

The precision countersink with uneven pitch and specially ground flutes shows perfect results in various materials such as general structural steels, non-ferrous metals and cast iron.

The uneven pitch guarantees smooth running and vibration-free operation;
Optimized flutes ensure perfect chip and heat removal;
Reduced feed force;
Ideal power transmission thanks to triangular shank;
AI-Cro coating - for smoother surfaces and longer tool life.

Set includes:
Plastic branded case and 6 countersinks made of high-quality high-speed steel HSS according to DIN 335. Type of countersinks - type C 90 °.
Diameters: Ø 6.3 - 8.3 - 10.4 - 12.4 - 16.5 - 20.5 mm.

Description:

1. Thanks to the grooves cut with CBN, the cutting edges are more sharp and without burrs, which provides high cutting ability and wear resistance of drills.

2. Radial CBN - occipital grinding allows to achieve high accuracy of the diameter of the cutting edge.

3. Each diameter has an axial projection, which ensures the accuracy of the drilling diameter.

4. The sight of a countersink with axial projections guarantees a clean drilling and less heat release.

5. Countersink, carved with CBN, guarantee excellent chip removal, provide work without burrs, have excellent centering.

Product Application:

1. The tool is successfully used in such industries as electrical engineering, plumbing, heating devices, car service, aviation production, electronics, etc.

2. The tool is suitable for working with conventional industrial materials, such as, for example, non-ferrous metals, tool steel, plastic, duroplastic, and sheet steel.
3. Suitable for deburring steel, cast steel, non-ferrous and light metals.

4. When the RUKO cooling spray or RUKO lubricating paste is used, the wear resistance of drills is significantly increased.

Important!
- use cooling lubricant when countersinking;
- to extend the service life of the countersink, do not use it at high speeds;
- the best results are achieved when working at low revs;
