Countersink Ø6.3 mm 90° DIN 335 C HSSE is a precision cutting tool designed for professional hole machining in difficult-to-machine materials. Made of high-performance cobalt-alloyed high-speed steel (HSSE), it provides increased wear resistance and excellent thermal stability during intensive operation.
Thanks to its 3 cutting edges, the countersink provides stable operation and efficient chip evacuation. This design minimizes vibration, resulting in a clean countersunk surface and less frequent tool replacement. Optimized cutting edge geometry enables precise centering and controlled machining without damaging the hole edge.
Countersink for metal is ideal for preparing seats for countersunk screws, particularly in stainless steel and alloys with increased hardness. Thanks to its robust construction and a high-quality surface, the user can rely on dependable performance even under the most demanding conditions.
The product meets DIN 335 C requirements, and its compact diameter allows use in precision applications on both conventional machines and modern CNC systems.
- High wear resistance – cobalt-alloyed HSSE steel provides durability when machining stainless steel and difficult materials.
- Stable operation – the three-edge design reduces vibration and improves hole finish quality.
- Versatile applications – ideal for metals, unalloyed steels, and stainless materials.
- Compliance with DIN 335 C – ensures dimensional repeatability and industrial compatibility.
Countersink Ø6.3 mm 90° for stainless steel is a dependable choice for professionals who expect productivity, durability, and precision in daily workshop and production operations.
