Accupro 75261743 TNMG332 Carbide Turning Insert

Product Description

The ACCUPRO 75261743 is a TNMG-style indexable carbide turning insert designed for external and internal turning operations on CNC and manual lathes. Conforming to ANSI code TNMG332 and ISO code TNMG160408, this triangular insert features a neutral hand orientation with a 0-degree relief angle (negative side clearance) and a PVD coating applied over a carbide substrate. The ACM25P grade delivers high wear resistance across a broad range of workpiece materials, making it a versatile choice for production turning. Each insert provides 6 usable cutting edges, reducing per-edge tooling cost. The 0.80 mm corner radius balances surface finish quality with edge strength in moderate-to-heavy feeds.

This insert is suited for turning steel, stainless steel, and special or super alloys in both residential-shop and production-floor environments. The IPR+ chip breaker geometry promotes reliable chip evacuation during continuous and interrupted cuts in ISO material groups P, M, and S. Compatible holding methods include clamp, lever lock, pin, and screw styles, giving machinists flexibility across a wide range of standard TNMG toolholders. Maximum depth of cut is 6.00 mm (0.2362 inches), appropriate for roughing through finishing passes depending on feed rate and material hardness.

Compatibility

Designed for use in standard TNMG-style toolholders accepting ANSI TNMG332 or ISO TNMG160408 inserts. Suitable for turning steel (ISO P), stainless steel (ISO M), and special or super alloys (ISO S).

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with indexable insert toolholders. Power down and lock out the machine before indexing or replacing inserts. Inspect the insert seat and clamping mechanism for debris or damage before seating a new insert. Handle carbide inserts with care to avoid chipping cutting edges during installation.
