Hole and countersink are produced in operation and precisely aligned. Therefore very sturdy and tight concentricity tolerances. Particulary suitable for NC machines due to high positional accuray, excellent centering properties and great sturdiness. The precending centering operation can thus often be omitted. For thread tapping drill holes to DIN 336 sheet 1 with 90° countersink. In the following operation, the tap therefore does not have to cut into the sharp edge of the hole.
