Accupro 75475772 VCMT331 Carbide Turning Insert

Product Description

The ACCUPRO 75475772 is a VCMT-style carbide turning insert designed for precision metal cutting in CNC and manual lathe operations. It features a V-shaped diamond (rhombic) 35-degree included angle geometry and a CVD coating applied over a carbide substrate, delivering high wear resistance with moderate toughness across a range of cutting conditions. The insert carries a corner radius of 0.0315 inches (0.80 mm) and a maximum depth of cut of 0.1181 inches (3.00 mm). With a neutral hand orientation and a positive side clearance, it is suited for finish to semi-finish turning passes. Machinists, toolroom technicians, and CNC operators install this insert in compatible VCMT toolholders on production lathes and turning centers.

This insert is engineered for cutting steel (ISO P) and stainless steel (ISO M) workpiece materials, targeting applications that demand high wear resistance transitioning to moderate toughness. The WM+ chip breaker geometry promotes chip control during steel and stainless steel turning. It is well suited for production turning operations where consistent surface finish and tool life are priorities. The ACM20P grade with CVD coating makes it appropriate for medium to high cutting speed ranges on both carbon and austenitic stainless steel stock. Each package contains one insert, with a minimum order quantity of 10 units.

Key Features

• CVD-coated carbide substrate in ACM20P grade for high wear resistance and controlled toughness
• V-diamond 35-degree geometry (VCMT style) with positive side clearance for efficient chip evacuation
• WM+ chip breaker promotes reliable chip control on steel and stainless steel
• Corner radius of 0.0315 inches (0.80 mm) for finish and semi-finish turning applications
• Maximum depth of cut of 0.1181 inches (3.00 mm)
• Two cutting edges per insert; screw-held mounting for secure clamping in compatible toolholders

Compatibility

Designed for use in VCMT-style turning toolholders accepting VCMT331 (ANSI) or VCMT160404 (ISO) inserts. Compatible with ISO P (steel) and ISO M (stainless steel) workpiece material groups as indicated by manufacturer grade and coating selection.

Installation Notes

This insert is installed and indexed by qualified machinists or CNC toolroom technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver or wrench for the insert clamping screw to ensure proper seating without overtightening. Inspect the insert pocket and clamping screw for wear or damage before installing a fresh cutting edge.
