With this robust tool, sheet metal can be centered, drilled, reamed and deburred in one operation. The deeply ground and spiral shaped chip groove offers absolute smoothness and high cutting performance. In particular, non breakable chips are cleanly removed, just like with a twist drill. This reduces the formation of built up edges and cold welding on the cutting edges. The cone makes it easier to
