Application: Specially designed for the highest demands in INOX steel, stainless steel and Hardox 400 as well as for all ferrous and non-ferrous metals, hard and soft plastics. 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.
