The invention relates to a drilling tool for hole-drilling in metallic materials, including a drill body (11) as well as at least one cutting insert (12) located in the front end thereof, defining the periphery of the drill, the drill body having a number of axially extending chip channels (14, 15) and bars (16, 17) situated therebetween. Characteristic of the new tool is that the drill body (11) has been provided with a damping unit (18) situated at an axial distance behind the cutting inserts in at least one chip channel which damping unit entirely or partly fills up a portion of said chip channel, and which damping unit is composed of two material portions (18a, 18b, 23a, 23b) made up of different rigidities. |
