The deep-ground and spiral-shaped clamping groove offers absolute smoothness and high cutting performance. In particular, chips that do not break are cleanly transported away as with a twist drill. This reduces the formation of surface-mounted cutting edges and cold welding on the cutting edges. The cone makes it easier to pull back when the metal sheet is drilled through.
