Accupro 75562660 CNMG432 Carbide Turning Insert

Product Description

The ACCUPRO 75562660 is a CNMG432 indexable carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. It carries an ISO designation of CNMG120408 and is manufactured in the ACM25P grade with a PVD coating for extended tool life. The insert features a diamond (rhombic) 80-degree shape, a neutral hand orientation, and a negative side clearance, making it suitable for general-purpose turning across a broad range of workpiece materials. With four usable cutting edges per insert, it delivers a low cost-per-edge for production environments.

This insert is rated for steel (P), stainless steel (M), and special and super alloys (S), covering high wear-resistance through moderate toughness applications depending on material class. It is intended for use on conventional and high-production CNC turning equipment where consistent surface finish and dimensional accuracy are required. The IPK+ chip breaker geometry is suited for medium to semi-finish turning passes. Machinists, tooling specialists, and CNC operators working in job shops, production facilities, and aerospace or energy component manufacturing will find this insert appropriate for their tooling programs.

Key Features

• ACM25P grade with PVD coating for high wear-resistance on steel and stainless steel
• Four cutting edges per insert for reduced tooling cost per edge
• IPK+ chip breaker optimized for medium to semi-finish turning
• Rated for P (steel), M (stainless steel), and S (super alloy) workpiece materials
• Compatible with clamp, lever lock, pin, and screw insert-holding methods

Compatibility

Designed as a replacement-style CNMG432 turning insert for toolholders accepting CNMG style inserts with clamp, lever lock, pin, or screw holding methods and a negative-rake seat configuration.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle locked before indexing or replacing inserts. Use the appropriate torx or hex key to torque the clamping screw or lever to the toolholder manufacturer's specification. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. Handle carbide inserts with care to avoid chipping the cutting edges.
