Set HSS-XE countersinks 90° RAPID-CUT

Art. 20.1651
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.

Content:
  • 6 HSS-XE Countersink DIN 335 Type C 90°, 3-Flat-Shank 20.1760:
  • 1 pc each Ø: 6,3 - 8,3 - 10,4 - 12,4 - 16,5 - 20,5 mm
Properties:
HSS-XE steel:
Made of high-alloyed special steel „XE“ for considerably longer service life than HSS-Steel.

RAPID-CUT specially developed for automatic and quick feed. Optimized
cutting geometry + 3 flat sections of the shank leads to:
• up to 30% faster sinking than conventional countersinks
• up to 40% higher service life




3-Flat shank for:
– Excellent torque transmission
– No slippage in the drill chuck
– This results to superior cutting output
* NOTE: In conversion.
Not yet available for all countersinks. If absolutely needed, please ask in advance if already avialable.
- According to the diameter radially-adjusted CBN ground relief.
  Result: The cutting edge is always the highest point of the diameter


- Each diameter receives its own relief angle.
  Result: The cutting edge is also always the highest point.
CBN deep-ground flutes leads (unlike miled grooves) to significantly smoother and sharper cutting edges. This result is: Higher cutting performance and tool life.


- Axial relief produces by CBN grinding leads to a smooth and low-heat cut.
