The deep-ground flutes of step drills with 3 cutting edges guarantee absolutely chatter-free working. The reduced load of the cutting edges allows a higher feed rate especially for soft materials like non-ferrous metals. The chamfer on the base of the cone makes withdrawal of the tool from the material simple when through hole drilling.
