Seven-edged countersink with pointed angle 90°, irregular pitch, with fully ground tool head for fi nest results. Countersinking in all sorts of wood, also suitable for veneered, laminated panels and many plastics like acrylic glass, Corian®, GFRP, HPL coating, polycarbonate, PVC and Trespa® board. Due to the specially designed pitch, it is possible to countersink without chattering also in soft wood. For hard plastics etc., we recommend the carbide tipped adjustable countersink VARIO 2202. Combine with depth stop 1621 for precise limiting of the countersink depth.
