The slots of Karnasch high-performance countersinks are always ground. This ensures excellent chip removal, vibration-free work, a scratch-free surface and better centering. Hss-xe steel + special high-alloy xe steel blue-tec coating for considerably longer service life.

The slots of Karnasch High-Performance countersinks are always ground in CBN. This guarantees: Excellent chip evacuation / work without vibrations / surface without scratches / better centering.

HSS-XE steel + BLUE-TEC coating

Made of special high-alloy XE“ steel for considerably longer service life than HSS steel.
BLUE-TEC coating for a substantial increase in service life also in dry machining (no/little cooling)

Triple flat shank for:
– Excellent torque transmission
– No slipping in the chuck
– This results in superior cutting performance

According to the diameter of the CBN soil relief radially adjusted.
Result: The cutting edge is always the highest point of the diameter.

Each diameter receives its own relief angle.
Result: the edge is also always the highest point.

Deep grinding CBN flutes lead (unlike milled flutes) to significantly smoother and sharper cutting edges. This result is: Greater cutting performance and tool life.

The axial relief produced by grinding CBN produces a smooth, low-heat cut.
