INNOT guide

Negative turning inserts: strong and double-sided

Negative inserts have a 0° clearance and can be used on both sides: a CNMG offers 4 edges, a TNMG and a WNMG 6, an SNMG 8. The edge is strong and withstands high depths of cut and feeds, which makes them the first choice for roughing and general turning on stable lathes.

The shape depends on the profile to be turned: 80° (C and W) to turn and face with the same tool, 55° (D) and 35° (V) for profiling, 90° (S) and 60° (T) for roughing with the most edges.
