Chip cutting tool with geometrically defined cutting edge - has aperture in chip removing face, close to cutting edge for swarf removal

摘要

The tool (10) has an aperture (32) in the chip removing face (36) at close spacing to its cutter edge (26), forming a removal facility for the swarf to a side opposite to the chip removing face, or towards a tool inner duct, leading away from a cutter wedge. The angle of the chip removing face section between the aperture and cutter edge is pref. kept relatively large, while the face angle of the cutter wedge is kept relatively small. USE/ADVANTAGE - For milling cutters etc., with improved swarf removal and long service life.
