Tips for Necking
Notes for Undercutting Recommended Chipbreaker: RN
Distance between Workpiece and Necking
| MIN | Edge Width CW (mm) | Depth of Necking APMX (mm) | Distance between Workpiece and Necking APMX2 (mm) | ||
| D | 2,0 | 1,50 | 0,646 | ||
| A | 3,0 | 2,00 | 0,793 | ||
| PMX | X2 | 4,0 | 2,50 | 0,939 | |

The recommended cutting conditions for necking are the same as grooving with RN type chipbreaker and edge width. To prevent interference with the work material, do not use the holder for less than the minimum cutting diameter (DMIN) as specified for GNGN type holders.
