HSS-XE Blue-Tec Coated Taper/Deburring Countersink, DIN 334, Type D, 60 Degree, Morse taper

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 particularly suitable for countersinking in threaded
core holes and countersinking in the tool making / jig making industry.

- 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.
