The flutes of Karnasch High-Performance countersinkers are always CBN ground. This guarantees: Excellent chip clearance / chatter-free working / scratch-free surface / best centering. CONTENT: 6 HSS-XE Countersink DIN 335 Type C 90Degrees, 3-Flat-Shank 201745:
1 pc each Diameter: 6,3 – 8,3 – 10,4 – 12,4 – 16,5 – 20,5 mm 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 Each diameter receives its own relief angle. Result: The cutting edge is also always the highest point. According to the diameter radially-adjusted CBN ground relief. Result: The cutting edge is always the highest point of the diameter Axial relief produces by CBN grinding leads to a smooth and low-heat cut. CBN deep-ground flutes leads (unlike miled grooves) to significantly smoother and sharper cutting edges. This result is: Higher cutting performance and tool life.
