Set 6 HSS-XE + BLUE-TEC coated countersinks 82°

Art. 20.1697
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.

  • 6 HSS-XE Countersink DIN 335 Type C 82°, 3-Flat-Shank 20.1745:
  • 1 pc each Ø: 1/4"- 5/16" - 3/8" - 1/2" - 5/8" - 3/4"
HSS-XE steel + BLUE-TEC coated:
Made of high-alloyed special steel „XE“ for considerably longer service life than HSS-Steel.
BLUE-TEC coating for a further substantial increase in service life also when machining dry (no/little cooling)

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.
