Roughing tool and method for its manufacture

Abstract

The invention relates to a method for producing a roughing tool (1), particularly a circular milling tool, comprising the following steps: fitting a lateral surface of a tool base body (10) that can be rotatably driven about an axis of rotation (2) with a number of cutting element blanks (20′) that are staggered in the axial and/or peripheral direction, such that a free edge of each cutting element blank (20′) protrudes out of the lateral surface in the mounted state; inserting a microtoothing comprising a plurality of axially spaced cutting teeth (21) into the respective free edges of the cutting element blanks (20′) by a material removal method, preferably by thermal machining, particularly preferably by eroding, in the premounted state on the tool base body (10). The invention further relates to a roughing tool produced by means of such a method.
