Accupro 75262360 CNMG432 Carbide Turning Insert

Product Description

The ACCUPRO 75262360 is a CNMG432 style indexable carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. Built to ANSI code CNMG432 (ISO CNMG120408), it features an 80-degree diamond (rhombic) insert shape with a neutral hand orientation and a 0-degree relief angle with negative side clearance. The insert carries an ACM25P grade with a PVD coating and an IPR+ chip breaker geometry, delivering high wear resistance across a broad range of cutting conditions. With four usable cutting edges per insert, this tooling offers cost-efficient performance in production turning environments.

This insert is suited for turning steel, stainless steel, and special or super alloys in both roughing and finishing passes. The ACM25P grade covers ISO material groups P, M, and S, making it a versatile option for shops running mixed-material workloads. Typical applications include shaft turning, facing, profiling, and contouring on CNC lathes. It is compatible with standard CNMG-style toolholders using clamp, lever lock, pin, or screw insert-holding methods.

Key Features

• ANSI CNMG432 / ISO CNMG120408 geometry with 80-degree diamond insert shape
• ACM25P carbide grade with PVD coating for high wear resistance and toughness balance
• IPR+ chip breaker for effective chip control across steel, stainless steel, and super alloys
• Four cutting edges per insert for extended tool life and reduced per-edge cost
• Negative side clearance with 0-degree relief angle suits heavy-duty and interrupted cuts
• Compatible with clamp, lever lock, pin, and screw toolholder holding methods

Compatibility

Designed for use with standard CNMG-style indexable turning toolholders accepting ANSI CNMG432 or ISO CNMG120408 inserts. Compatible toolholders use clamp, lever lock, pin, or screw insert-holding methods. Applicable to ISO material groups P (steel), M (stainless steel), and S (special and super alloys).

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque-limiting wrench or screwdriver specified by the toolholder manufacturer to seat the insert securely without over-tightening. Inspect the insert pocket and seating surface for chips or debris before installing a fresh cutting edge.
