Tapered countersink fi 6.3 mm 90 degrees DIN 335 C HSSE is a precision cutting tool designed for professional machining of holes in difficult-to-machine materials. Made of high-performance cobalt-enhanced high-speed steel (HSSE), it provides increased wear resistance and excellent thermal stability during intensive use.

Thanks to the use of 3 blades, the countersink features stable operation and efficient chip removal. This design minimizes vibration, resulting in a clean countersinking surface and less frequent tool changes. Optimized blade geometry allows for precise centering and controlled machining without damaging the edge of the hole.

The tapered metal countersink is ideal for preparing sockets for countersunk screws, especially in stainless steel and high-hardness alloys. Thanks to its robust design and high-quality surface, the user is assured of reliability even in the most demanding conditions.

The product meets the requirements of DIN 335 C, and its compact diameter allows it to be used in precision applications - both on conventional machines and in modern CNC systems.

  • High wear resistance - HSSE steel with added cobalt ensures durability when machining stainless steel and difficult materials.
  • Work stability - three-edge design reduces vibration and improves hole finish.
  • Versatility of use - ideal for metals, unalloyed steels and stainless materials.
  • Compliance with DIN 335 C - guarantees dimensional repeatability and industrial compatibility.

The fi 6.3 mm 90-degree conical countersink for stainless steel is a sure choice for professionals who expect performance, durability and precision in their daily workshop and production work.
