Accupro 75261065 CNMG432 Carbide Turning Insert

Product Description

The ACCUPRO 75261065 is a CNMG432 indexable carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured in the CI series with a PVD coating and ACS15M grade, this insert delivers high wear resistance with moderate toughness. The diamond (rhombic) 80-degree insert shape provides a strong cutting edge geometry suited to finishing and semi-finishing passes. With a 0.80 mm (0.0315 inch) corner radius and a maximum depth of cut of 3.00 mm (0.1181 inches), it is well matched to medium stock removal applications. Licensed machinists and CNC turning operators install this insert as a direct toolholder replacement during routine indexing or tool change operations.

This insert is rated for primary use on stainless steel (ISO material group M) and special and super alloys (ISO material group S), where high wear resistance and controlled toughness are required. The IPE+ chip breaker geometry supports effective chip evacuation during these demanding cuts. With 4 indexable cutting edges and negative side clearance, it maximizes tool life per insert in high-production turning environments. It is sold individually with a minimum order quantity of 10 pieces.

Compatibility

Designed as an OEM-style replacement indexable turning insert for CNMG432 toolholders accepting negative rake carbide inserts with clamp, lever lock, pin, or screw holding methods.

Installation Notes

Installation is performed by qualified CNC machinists or turning technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert key specified by the toolholder manufacturer when securing the clamping screw or lever. Inspect the toolholder pocket for wear, damage, or debris before seating the new insert to ensure proper contact and cutting edge alignment.
