CUTTING TOOL AND METHOD OF MANUFACTURING A CUTTING TOOL

摘要

The present invention provides in various aspects a cutting tool which comprises a cutting tool insert (210) with a tip portion of cBN material having a cutting edge (216) formed therein and a base portion forming a sintered composition with the tip portion, and a body portion (220) coupling the cutting tool insert with a shank of the cutting tool, wherein the cutting tool insert (210) has a rake face (212) and a first flank face (214) defining the cutting edge (216). In one aspect, the rake face (212) has a negative rake angle relative to an axis parallel to a centre axis of the body portion. In another aspect, a second flank face (218) defining a further edge with the first flank face is formed such that the cutting edge (216) and the further edge do not have a common vertex. Herein the second flank face (218) is tilted with respect to an axis parallel to a centre axis of the body portion (220) by an angle greater than 0o.
