HSSE-VAP 90° Countersink 20.5 mm (for M 10) - for Stainless Steels
The BAER countersink is a tool for making tapered offsets or for precise deburring of bores. A hole in metal should always be deburred with a countersink, as the edges of the hole are very sharp. This is useful both to avoid cutting injuries and to achieve a flat surface.
If the screw is to be countersunk into the workpiece, the hole is pre-machined with a countersink. The hole is then drilled out conically to countersink the countersunk screws into the material. In this way, the screw head is flush with the surface of the workpiece.
For countersinking in stainless steel, a special tool material is required. The countersinks are made of cobalt alloyed high speed steel and vaporised surface. With their special geometries, they meet the requirements for machining difficult-to-machine materials such as stainless steel. Best results are achieved at low cutting speeds. Suitable for stainless steels V2A, V4A, INOX and high-strength steels.
