TNMG 160404

ISO Designation: TNMG 160404

TNMG 160404 is a triangular negative turning insert from the TNMG family, with its ISO 1832 code (160404) defining size, thickness and corner radius.

TNMG inserts use a 60° triangular negative geometry, giving three cutting edges per face and a versatile approach-angle range that suits general and semi-finish turning across steel, stainless steel and cast-iron components. The triangular shape is a common first choice in job shops that need one insert style to cover several turning operations on a single machine.

Per ISO 1832, the leading letters of this code indicate a triangular (60°) insert shape with a 0° (negative) relief angle; the remaining characters set the tolerance class, fixing style, size, thickness and corner radius.
