Accupro 75333096 CNMG432 Carbide Turning Insert

Product Description

The ACCUPRO 75333096 is a CNMG432 style carbide turning insert designed for precision metal cutting on CNC and manual lathes. It features a diamond (rhombic) 80-degree insert shape with a neutral hand orientation and four usable cutting edges, maximizing tool life per insert. The grade is ATP15M, uncoated carbide, with an inscribed circle of 0.5000 inches and a corner radius of 0.0315 inches (0.80 mm). Insert thickness is 0.1874 inches. This insert is held via clamp, lever lock, pin, or screw configurations, making it compatible with a wide range of standard CNMG toolholders used in production turning applications.

This insert is suited for turning steel, stainless steel, and cast iron workpieces in both residential shop and industrial production environments. The ATP15M grade delivers high wear resistance against steel and stainless steel, and high wear resistance against cast iron, making it a practical choice for machinists running mixed-material production. A maximum depth of cut of 0.0787 inches (2.00 mm) is recommended. The EN-JF chip breaker geometry supports controlled chip evacuation during finishing and semi-finishing passes.

Key Features

• CNMG432 ANSI insert code / CNMG120408 ISO insert code for broad toolholder compatibility
• ATP15M uncoated carbide grade with high wear resistance on steel, stainless steel, and cast iron
• Four cutting edges per insert reduce per-edge tooling cost
• Neutral hand orientation fits left-hand or right-hand CNMG toolholder pockets
• EN-JF chip breaker geometry supports finishing and semi-finishing cuts
• Negative side clearance (clearance code N, tolerance code M) for rigid, stable clamping

Compatibility

Designed as a direct-fit replacement for standard CNMG432 (ISO CNMG120408) toolholders using clamp, lever lock, pin, or screw holding methods. Verify toolholder pocket geometry and tolerance class before installation.

Installation Notes

CNMG turning inserts are installed by qualified machinists or toolroom personnel. Power down and lock out the machine before seating or removing inserts. Use the appropriate torque wrench and manufacturer-specified insert screw or clamp hardware for the toolholder design. Handle carbide inserts carefully to avoid chipping cutting edges during installation.
