Iscar 5503666 Wnmg 432-NF IC-530N Cermet Turning Insert

Product Description

The ISCAR 5503666 is a WNMG 432-NF IC-530N cermet turning insert designed for precision metal cutting in CNC lathe and turning center applications. Featuring a PVD-applied TiCN and TiN coating over a cermet substrate, this insert delivers wear resistance and thermal stability when machining stainless steel and carbon steel. The 80-degree trigon (W) shape with a neutral 0-degree relief angle and a 0.031-inch corner radius makes it well suited for finishing and light roughing passes. It belongs to ISCAR's Isoturn series and holds an ISO 13399-compliant designation of WNMG 432-NF. Licensed machinists and CNC operators working in job shop or production environments will find it compatible with standard WNMG toolholders.

This insert is intended for turning, facing, and boring operations on stainless steel and steel workpieces in both residential-scale job shop and industrial production settings. The NF chip breaker geometry supports positive-rake cutting action, which reduces cutting forces and helps control chip formation at moderate feed rates. The insert is held in place by clamp or pin methods, standard on most WNMG-compatible toolholders. It is part of ISCAR's Isoturn series, which covers a broad range of external and internal turning applications. Boring is listed as a confirmed multi-use application for this insert.

Key Features

• Cermet substrate with PVD TiCN and TiN coating for extended tool life on steel and stainless steel
• NF chip breaker geometry promotes positive-rake cutting and effective chip control
• 80-degree trigon insert shape (W) provides two usable cutting edges per insert
• 0.031-inch corner radius balances surface finish quality with edge strength
• Compatible with clamp and pin holding methods on standard WNMG toolholders
• ISO 13399 compliant; Iso Code WNMG 432-NF for straightforward toolholder matching

Compatibility

Designed as an OEM-style replacement or direct-use insert for standard WNMG toolholders accepting a 432 insert size. Primary workpiece materials are stainless steel (ISO material code M) and steel (ISO material code P). Boring is a confirmed secondary application.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always index or replace inserts with the machine powered down and the spindle locked. Use the correct torque wrench and manufacturer-specified seating hardware when securing the clamp or pin to avoid insert movement under cut. Inspect the insert seat and toolholder pocket for debris or damage before seating a new insert, as a contaminated pocket will affect tool life and surface finish.
