Application

For producing 90° counterbores up to 1300 N/mm².

Execution

profile-ground triple-edge countersink with radial relief, with extremely uneven pitch

Advantage

radial relief ensures optimum chip breaking
Uneven pitch ensures excellent surfaces without chatter marks and minimisation of cutting forces
3-sided shaft ensures very good power transmission and prevents the tool from spinning in the drill chuck or cordless drill
