HSS-XE Blue-Tec Coated Taper/Deburring Countersink, 60 Degree, DIN 334, Type C
The flutes of Karnasch high-performance countersinker are always CBN ground. This guarantees: Excellent chip clearance / chatter-free working / scratch-free surface / best centering.
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].
60Degrees countersinks are particulary suitable for countersinking in threaded core holes and countersinking in the tool making / jig maling industry.
CBN deep ground flutes results to extremely sharp cutting edges. This leads to: Burr- and chatter-free deburring and countersinking.
3-flat shank for:
- Excellent torque transmission
- No slippage in the drill chuck
- This results to superior cutting output.
- Each diameter receives its own relief angle.
Result: The cutting edge is also always the highest point.
- Axial refief produces by CBN grinding leads to a smooth and low-heat cut.
- According to the diameter radially adjusted CBN ground relief.
Result: The cutting edge is always the highest point of the diameter.
CBN deep-ground flutes leads [unlike miled grooves] to significantly smoother and sharper cutting edges. This result is: Higher cutting performance and tool life.
For countersinking in materials: - Stainless steel [V2A / V4A] - Steel - Cast iron - Non ferrous material
