Accupro 75333047 CNGP120402 Carbide Turning Insert

Product Description

The ACCUPRO 75333047 is a CNGP-style carbide turning insert designed for precision metal cutting on CNC and manual lathes. It carries the ISO designation CNGP120402 and features an 80-degree diamond (rhombic) insert shape with a 0.20 mm (0.0079 inch) corner radius, a 0.5000 inch inscribed circle, and a 0.1874 inch insert thickness. The PVD coating and ACM20K grade deliver high wear resistance with moderate toughness, making it well suited for interrupted and continuous turning operations on stainless steel and cast iron workpieces.

This insert is intended for use in turning operations on stainless steel (ISO material group M) and cast iron (ISO material group K) in both production and job-shop environments. It is installed by machinists and CNC operators in toolholders designed to accept CNGP-profile inserts. The maximum depth of cut is 2.50 mm (0.0984 inch). With four available cutting edges, this insert provides extended service life per unit and reduces tooling cost per part. The EXK+ chip breaker geometry supports chip control across a range of feed rates and depths.

Key Features

• ISO designation CNGP120402 with ANSI code CNGP430.5 for direct cross-reference
• ACM20K grade with PVD coating for high wear resistance on stainless steel and cast iron
• 80-degree diamond (rhombic) insert shape for strong cutting-edge geometry
• Four cutting edges per insert for extended tooling value
• EXK+ chip breaker for effective chip control during turning
• Compatible with clamp, lever lock, pin, and screw insert-holding methods

Compatibility

Designed as an OEM-style replacement turning insert for toolholders accepting CNGP-profile inserts with a negative side clearance, tolerance code G, and a 0.5000 inch inscribed circle. Suitable for stainless steel (M) and cast iron (K) workpiece materials.

Installation Notes

Installation is performed by machinists and CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before indexing or replacing the insert. Use the appropriate insert-holding method supported by the toolholder — clamp, lever lock, pin, or screw — and torque fasteners per the toolholder manufacturer's specifications. Inspect the insert seat and shim for debris or damage before seating a new cutting edge.
