Accupro 75283176 WNMG331 Carbide Turning Insert

Product Description

The ACCUPRO 75283176 is a WNMG-style indexable carbide turning insert designed for external turning operations on CNC and manual lathes. Carrying the ANSI code WNMG331 and ISO code WNMG060404, this insert features a W-shaped trigon body with an 80-degree included angle and a neutral hand orientation. The CVD coating and ACP15K grade deliver high to moderate wear resistance across a range of workpiece materials. With six cutting edges per insert and a negative side clearance geometry, it maximizes tool life per unit. Machinists and CNC operators working in production and job-shop environments install this insert in compatible WNMG toolholders.

This insert is suited for turning steel, stainless steel, and cast iron workpieces, corresponding to ISO material groups P, M, and K. The WL+ chip breaker geometry supports controlled chip evacuation during general-purpose turning passes. Maximum depth of cut is 0.0787 inches (2.00 mm), making it appropriate for finishing and light to moderate roughing passes. It fits standard WNMG toolholders accepting clamp, lever lock, pin, or screw holding methods.

Key Features

• ANSI code WNMG331 / ISO code WNMG060404 for direct toolholder cross-reference
• CVD-coated ACP15K carbide grade for high wear resistance on steel, stainless steel, and cast iron
• Six cutting edges per insert for extended tool life and lower cost per edge
• W-shaped trigon body with 80-degree included angle and 0.0157-inch corner radius for general-purpose turning profiles
• WL+ chip breaker supports chip control across P, M, and K material groups
• Compatible with clamp, lever lock, pin, and screw toolholder clamping systems

Compatibility

Designed as a direct-fit replacement for WNMG331 / WNMG060404 toolholders accepting negative-rake, neutral-hand carbide turning inserts with clamp, lever lock, pin, or screw holding methods.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench or insert key for the clamping screw to avoid seat damage — follow the toolholder manufacturer torque specification. Inspect the insert pocket seat for chips or debris before seating a new insert, as contamination will affect runout and surface finish.
