Product description

The countersinks work with significantly reduced axial forces. Their cutting edges are unevenly spaced. With the selected pitch, the axial force is reduced by more than 50 percent and the radial force by 25 percent, compared to conventional countersinks. The result: significantly less vibration on the tool.
