Accupro 75282723 Carbide Turning Insert WNMG431

Product Description

The ACCUPRO 75282723 is a carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It conforms to ANSI code WNMG431 and ISO code WNMG080404, with a W-shape trigon 80-degree geometry and a negative side clearance. The insert carries a CVD coating and is graded ACP15K, targeting high wear-resistance to moderate wear-resistance and toughness across steel, stainless steel, and cast iron workpiece materials. With 6 cutting edges per insert, the 75282723 offers extended tool life between change-outs. Machinists and CNC operators in production and job-shop environments install these inserts as part of a qualified toolholder system.

This insert is suited for general turning operations on steel (P), stainless steel (M), and cast iron (K) workpieces. The WL+ chip breaker geometry helps manage chip flow during medium-depth passes. A maximum depth of cut of 0.0787 inches (2.00 mm) and a 0.0157-inch corner radius make it appropriate for semi-finish to finish turning applications. It fits any compatible toolholder accepting WNMG431 inserts with clamp, lever lock, pin, or screw holding methods.

Key Features

• ANSI code WNMG431 and ISO code WNMG080404 geometry for broad toolholder compatibility
• CVD coating on carbide substrate for high wear-resistance across P, M, and K workpiece materials
• 6 cutting edges per insert for extended cost-per-edge value
• WL+ chip breaker designed for controlled chip formation during turning operations
• Negative side clearance with M tolerance code for consistent, repeatable seating
• Maximum depth of cut 0.0787 inches (2.00 mm), suited for semi-finish and finish turning

Compatibility

Designed as a direct-fit replacement for WNMG431 and WNMG080404 style inserts in any toolholder accepting a W-shape trigon insert with clamp, lever lock, pin, or screw holding methods.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist or CNC tooling technician with the machine powered down and the spindle locked. Use the appropriate torque wrench and manufacturer-specified insert clamping hardware for the toolholder in use. Inspect the insert seat and pocket for debris or wear before seating a new insert. Handle carbide inserts with care to avoid chipping the cutting edges prior to installation.
