Due to the more stable neck of the conical tool you can increase the feet per tooth by max. 20% or increase ap max. 10%. You can increase the speed up to 400% in HSC machining. The radial cutting depth ae should be in a lower range. HPC Recommended cutting data for solid carbide end mills with corner radius 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
