HSS ground metal drills are made from high speed steel. Full grinding during the manufacturing process results in a very sharp drill with high precision. The split point ensures self-centering and allows holes to be drilled without vibration. When used in combination with cutting oil (90483.000.407, 90019.000.105), this results in a significantly longer tool life.
