Iscar 5567523 WNMG432-M3P IC8250 Turning Insert Carbide

Product Description

The ISCAR 5567523 is a WNMG432-M3P IC8250 grade solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN that provides wear resistance, thermal stability, and a low-friction surface for extended tool life. The 80-degree trigon (W-shape) insert geometry with a 0.0315-inch corner radius and M3P chip breaker makes it well-suited for medium roughing and finishing passes. Licensed machinists and CNC operators install this insert in compatible WNMG-style toolholders as a line-replaceable cutting element.

This insert is engineered for turning stainless steel and carbon and alloy steel workpieces, covering ISO material groups M and P. It fits the ISCAR Isoturn series and is intended for medium-duty interrupted or continuous turning applications in job shops, production machining facilities, and aerospace or industrial component manufacturing environments. The M3P chip breaker geometry controls chip flow across a broad feed and depth-of-cut range, making it a practical choice where operators run varied cutting parameters on the same toolholder.

Key Features

• IC8250 grade with CVD TiCN / Al2O3 / TiN multilayer coating for wear and heat resistance
• WNMG432 geometry: 80-degree trigon shape, 0.0315-inch (0.80 mm) corner radius
• M3P chip breaker for reliable chip control on steel and stainless steel
• Maximum depth of cut 0.157 inch (4.00 mm)
• Positive rake geometry reduces cutting forces on the workpiece
• Conforms to ISO 13399 insert identification standard

Compatibility

Designed as an OEM-style replacement insert for WNMG-style turning toolholders in the ISCAR Isoturn series; confirm toolholder seat size and clamping style before installation.

Installation Notes

Turning inserts are installed and indexed by qualified CNC machinists or tool-crib technicians. Power down and lock out the machine spindle before changing inserts. Use the manufacturer-specified torque wrench and clamping screw to seat the insert firmly without over-torquing. Inspect the insert seat and chip pocket for debris before seating a new insert to ensure proper contact and runout.
