Conical and deburring countersink bit
Secure power transfer and fast counter-sinker replacement due to 1/4" bit six-edged shaft
For deburring, countersinking, deep countersinking countersunk screws in compliance with DIN 335.
� 90° countersink angle
� 3 cutter geometry with cylindrical shaft
(DIN 335 Form C)
� Chip flutes and cutting edges ground from the
fully hardened material using CbN process (cubic
crystalline boron nitride)
Optimum dimensional accuracy and sharpness,
vibration-free drilling progress, high surface finish
Conical and deburring countersink HSS CbN
� Axial relief ground cutting edge for jolt-free
operation
� Increased working life and cutting speed due to
use of bTI drill and cutting oil
