Countersink Ø30 mm 90° DIN 335 C HSS is a versatile cutting tool designed for machining metals, including stainless steel and non-ferrous metals, as well as plastics. The tool meets the requirements of DIN 335 C and is equipped with three precision cutting edges, which significantly improve operating stability and produce clean, repeatable results.
Application countersink for metal enables countersinking of holes for countersunk screws and edge chamfering. Cutting edges with an optimized rake angle ensure smooth entry into the material and efficient chip removal, minimizing the risk of damage to the machined surface.
High-quality working surface made of hardened high-speed steel (HSS) provides increased abrasion resistance and long service life when operating under moderate thermal loads.
- Three cutting edges – ensure stable, quiet operation without vibration and a uniform hole finish.
- High-quality HSS steel – enables durable, efficient machining of medium-hardness metals.
- Smooth cutting surface – ensures a clean finish and easy chip evacuation.
- Wide range of applications – works well in both one-off and series production.
- Suitable for stainless steel – allows use as a Ø30 mm 90° countersink for stainless steel.
Ø30 mm 90° countersink is a reliable choice for professional users seeking a high-quality finish and dependable tool performance under various machining conditions.
