BOHRCRAFT conical multi-tooth countersink Ø 10.4 mm DIN 335C form C 90° HSS Co8 for Hardox

BOHRCRAFT conical multi-tooth countersink Ø 10.4 mm DIN 335C form C 90° HSS Co8 for Hardox.  
Multi-tooth cobalt countersink for precise taper holes and countersinking in hardened, high-strength Hardox steel. It is made of high-speed cobalt steel HSSE HSSCo8 and has a ZrN+ (zirconium nitride) coating, which increases the wear resistance of the working surfaces. The countersink has a countersinking angle of 90° and 5 cutting teeth. The shank with a diameter of 10 mm is equipped with three anti-rotation planes. Designed for use on drilling machines, lathes and milling machines without numerical software control. Suitable for processing Hardox 400, Hardox 450 and Hardox 500 steels. Not recommended for hand and cordless drills due to the brittleness of HSSCo8 steel and possible damage to the cutting edges from vibration and shock loads.
