Set carbide tipped + BLUE-TEC coated countersinks 90°

Art. 20.1648
Product details:

The flutes of Karnasch High-Performance countersinkers are always CBN ground. This guarantees: Excellent chip clearance / chatter-free working / scratch-free surface / best centering.

  • 5 HSS-XE Countersink DIN 335 Type C 90°, 3-Flat-Shank 20.1755:
  • 1 pc each Ø: 6,3 - 10,4 - 16,5 - 20,5 - 25 mm
Tungsten Carbide + BLUE-TEC coated:
Made of tungsten carbide for maximum tool life, even in most difficult materials.
BLUE-TEC coating for a further substantial increase in service life also when machining dry (no/little cooling).
  • Ø 4,3-11,5 mm solid carbide
  • Ø 12,4-31 mm brazed shank

- Each diameter receives its own relief angle.
  Result: The cutting edge is also always the highest point.
- According to the diameter radially-adjusted CBN ground relief.
  >Result: The cutting edge is always the highest point of the diameter.

- Axial relief produces by CBN grinding leads to a smooth and low-heat cut. CBN deep-ground flutes leads (unlike miled grooves) to significantly smoother and sharper cutting edges. This result is: Higher cutting performance and tool life.
