35° rhombic turning insert. We make 10 VNMG sizes, from VNMG12T302 to VNMG160412. Grade, coating and chipbreaker are matched to your material and operation.
What VNMG means
The first four letters of an ISO 1832 designation give the shape, the clearance angle, the tolerance class, and the hole and chipbreaker.
| Code | Feature | Meaning |
|---|---|---|
| V | Shape | 35° rhombic |
| N | Clearance angle | 0° (negative insert) |
| M | Tolerance class | Class M |
| G | Hole and chipbreaker | Cylindrical hole, chipbreaker on both faces |
Where VNMG inserts are used
The 35° corner gives the most access for profiling and copying fine contours, but it is the weakest of the common corners, so it is used for light cuts and finishing.
VNMG is a negative 35° rhombic turning insert. It has a cylindrical hole. It has a chipbreaker on both faces. It can be turned over, so both faces are used: twice the corners of a one-sided insert.
Choose the size for your depth of cut, the corner radius for the feed and finish, and a holder made for VNMG inserts of that size.
