The 90° countersink set consists of five conical countersinks in dimensions between 6.3 mm - 25.0 mm.
90° countersinks are tools for making conical offsets or for precise deburring of bores. A hole in metal should always be deburred with a countersink, as the edges of the hole are very sharp. This is useful both to avoid cutting injuries and to achieve a flat surface.
If the screw is to be countersunk into the workpiece, the hole is pre-machined with a countersink. The hole is then drilled out conically to countersink the countersunk screws into the material. In this way, the screw head is flush with the surface of the workpiece.
