Accupro 75242339 WNMG432 Carbide Turning Insert Cvd

Product Description

The ACCUPRO 75242339 is a WNMG432 indexable carbide turning insert designed for external and internal turning operations on steel and stainless steel workpieces. It carries the ACM20P manufacturer grade with a CVD coating, placing it in the high wear-resistance to moderate toughness range for ISO material groups P and M. The W-style trigon body features an 80-degree included angle and a negative side clearance, delivering stable cutting geometry across a wide range of lathe applications. With six cutting edges per insert, this single-sided neutral-hand insert offers extended tool life per unit. Machining professionals running production or job-shop turning operations will find this insert well suited to medium-finishing and semi-roughing passes.

This insert is intended for turning centers and manual lathes where a WNMG-style toolholder is in use. The ACM20P CVD grade is optimized for steel and stainless steel, making it a practical choice for ISO P and M material groups in both continuous and mildly interrupted cut conditions. The IPK+ chip breaker geometry supports chip control across a range of feed rates and depths of cut up to 0.1654 inches. Compatible holding methods include clamp, lever lock, pin, and screw-style toolholders that accept WNMG insert geometry.

Installation Notes

Installation is performed by a machinist or toolroom technician familiar with indexable insert tooling. Ensure the lathe or turning center is powered down and the spindle is fully stopped before indexing or replacing inserts. Use the appropriate torque driver for screw-lock or lever-lock holders per the toolholder manufacturer guidelines. Inspect the insert pocket and seating surface for debris or wear before seating a new insert to maintain proper cutting geometry.
