Abstract (en)

[origin: WO9408745A1] An end mill which both drills and mills has main cutting edges (4) and end cutting edges (5) as well as reinforcing chamfers (6) between these. The end mill consists of a core of high speed steel or tool steel and an over-lying layer made of a hard material with 30-70 % by volume of sub-micron hard constituents in the form of carbides, nitrides and/or carbonitrides of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and/or W in a metallic matrix based on Fe, Co and/or Ni, whereby the external surface of the overlying layer at least partly is coated with a thin layer of TiN, Ti(C,N) and/or (Ti,Al)N. The tool's pitch angle is 40 +/- 5 DEG and its rake angle is 12 +/- 5 DEG .
