| side) with truncated radii – a configuration which | • Increased cutting speed (due to better heat transfer) |
| facilitates heat transfer from the cutting area. | • Reduced notch wear (due to 45º approach angle) |
| The two edges without chipbreakers (flat) are not used. | • Increased feed (the 45° approach angle produces |

JHP tools. The standard seats should be replaced with the special ones which have a pin whose purpose is to prevent using the non-working flat cutting corners. Chipbreaking Range SNMG 120408-EM-R
