Tapered countersink fi 8,3 mm 90 degrees DIN 335 C HSS is a specialized cutting tool, designed for precision machining of holes at ninety degrees. Made of HSS high-speed steel in accordance with DIN 335 C, it provides high resistance to temperature and dynamic loads during intensive work.
The tool is equipped with 3 blades that effectively stabilize the cutting process, minimizing vibration and ensuring perfect surface finish. This makes it possible to achieve high dimensional repeatability and smoothness, resulting in higher quality machining and fewer tool changes.
The tapered metal countersink is ideal for both countersinking holes for countersunk screws and for deburring or leveling faces. The product is applicable for work with a variety of materials - from unalloyed steels to non-ferrous metals - and is especially recommended as a conical countersink fi 8.3 mm 90 degrees for stainless steel, where high surface quality is crucial.
The tool can be used on conventional machine tools, bench-top drills, as well as modern CNC machining centers. The high quality countersink surface reduces material adhesion and promotes efficient chip removal.
- Stable tool operation - three-edge design minimizes vibration and improves face quality.
- High wear resistance - HSS steel guarantees durability when working with metals and stainless steel.
- Universal application - ideal for countersinking, chamfering and deburring in various materials.
- DIN 335 C standard - ensures full compliance with industrial technical requirements.
Conical countersink fi 8.3 mm 90 degrees is a reliable choice for professionals who expect high precision and long tool life.
