90° countersinks and deburring countersinks, HSS-E PM.Design: Axial and radial relief ground and CBN deep-ground. With straight, u-shaped flute length and flutes ground from solid. Also provided with cutting and clearance angles for the most common materials.Application: Specially designed for the highest demands in INOX steel, stainless steel and Hardox 400. For universal chatter and burr-free drilling, countersinking and deburring work for countersunk screws DIN 963, DIN 964, DIN 965, DIN 966 and DIN 7991 in one step. Please note the large countersink range! The excellent cutting properties and easy machining process result from the cone-shaped relief grinding on the coat and angle of rake. The countersink achieves the best results with the strongest feed and lowest cutting speed.Note: Sufficient supply of coolant is essential. HSS-E PM has, in comparison to conventional HSS steels, a consistent, fine grained material structure. This means they have good hot hardness, pressure resistance and resistance to wear.
