Countersink 90°

Seven-edged countersink with pointed angle 90°, irregular pitch, with fully ground tool head for finest 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. Absolutely chatter-free countersinking due to 7-edged head geometry with unequal pitch.
