TiN/ Z HA
HSS
ZrN 3
Application: Advantage:
For producing 60° counterbores up to 1300 N/mm . 2 ƒ Radial relief ensures optimum chip breaking
Execution: ƒ Uneven pitch ensures excellent surfaces without chatter marks and minimisa-
tion of cutting forces
ƒ Profile-ground triple-edge countersink with radial relief, with extremely uneven ƒ 3-sided shaft ensures very good power transmission and prevents the tool from
pitch spinning in the drill chuck or even in the cordless drill
