HSS-XE + BLUE-TEC coated Taper and deburring Countersink work standard Type C 120°, 3-Flat-Shank

Art. 40.3040
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.

Properties:
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.
