FORMAT HSS TiN 120° tapered countersink 8,3mmTapered countersink 120°, with cylindrical shankMakeup: axially and radially ground. With a straight U-shaped chip groove and chip chambers ground from solid material. In addition, due to its rake and touch angle, it is suitable for most materials used.Application: universal, for countersinking and notch- and burr-free deburring of countersunk screw holes according to DIN 963, DIN 964, DIN 965, DIN 966 and DIN 7991 in one pass. Note the size of the countersinking range!Excellent cutting properties and trouble-free chip evacuation due to the tapered grinding and rake angle. The countersink achieves best results at high feed and low cutting speed.Note: Ensure sufficient coolantNominal Ø: 8.3 mmSmallest Ø: 2.2 mmTotal length: 48.5 mmShank Ø: 6 mmsteels < 700 N/mm²: suitablesteels < 1000 N/mm²: recommendedINOX ferrite./martenz.: suitableAluminum < 8% silicon: recommendedAluminum > 8% silicon: recommendedCopper alloys: suitableCoating: TiN
