6 VHM BLUE-TEC coated 90Degrees, cylindrical shank 40.3045:
Je 1 pc each Diameter: 10,4 - 12,4 - 16,5 - 20,5 -25,0 mm:

Tungsten carbide + BLUE-TEC coated

4 + 5 cuts for difficult machine materials:
BLUE-TEC coating for a further substantial increase in service life also when machining dry (no/less cooling)

10,4 mm solid carbide

12,4-31,0 mm brazed shank

Tungsten carbide countersinks Art. 40 3045 comes with cylindrical shank.
This countersink type is used mostly on CNC machines with shrinking chucks.
Shrinking chucks works only with cylindrical shank.

Attention:

Solid carbide countersinks should be only used on CNC machines.

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.

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.
