Abstract

A rotary tool for drilling and chamfering, which takes place in one common advance, essentially comprises a base body, a drill clamped centered therein and a chamfering tool disposed on the end of the base body toward the drill tip and having a cutter body tip disposed next to the flank of the lateral free face of the drill. The chamfering tool can be radially adjusted in relation to the drill in a direction pointing at right angles in respect to the drill axis.
