Countersink fi 31 mm 120° DIN 347 A HSS is a professional cutting tool designed for precise face machining around holes. Its design features three ground cutting edges, providing exceptional stability during operation, which directly results in higher countersinking quality and less frequent tool replacement.
Made of wear-resistant high-speed steel (HSS), Ø31 mm 120° countersink performs excellently when machining stainless steel, carbon steel and difficult-to-machine materials. The tool retains its sharpness and hardness even at temperatures approaching six hundred degrees Celsius, making it an ideal choice for operation at high cutting speeds.
High quality working surface reduces workpiece material adhesion, supports chip evacuation and ensures machining repeatability even in large production runs.
- Three cutting edges for stable operation – enable smooth, controlled machining without vibration.
- High durability of HSS steel – ensures long tool life under demanding conditions.
- Resistance to high temperatures – the tool retains its cutting properties even during intensive cutting.
- Compliance with DIN 347 A – facilitates integration with industrial tooling systems.
Countersink for metal ensures repeatable results and minimizes production losses. For demanding users Ø31 mm 120° countersink for stainless steel provides a reliable solution for precise, economical machining.
