Solid Carbide Step Drills
Overview: The solid carbide step drill is suitable for drilling countersunk holes. As diameter d3 is ground without guide lands, the solid carbide step drill is not suitable for counterboring. Any step angle between 60° and 120° may be selected. The cutting data must always be based on the step diameter d1.
