DNMG inserts
55° rhombic turning insert. We make 14 DNMG sizes, from DNMG110404 to DNMG150616. Grade, coating and chipbreaker are matched to your material and operation.
What DNMG 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 |
|---|---|---|
| D | Shape | 55° rhombic |
| N | Clearance angle | 0° (negative insert) |
| M | Tolerance class | Class M |
| G | Hole and chipbreaker | Cylindrical hole, chipbreaker on both faces |
Where DNMG inserts are used
The 55° corner reaches into profiles, tapers and recesses that an 80° corner cannot, but the corner is weaker; use it where the contour needs that clearance.
DNMG is a negative 55° 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 DNMG inserts of that size.
