Seco 00023688 WNMG432-M5 TP40 Turning Insert Carbide

Product Description

The SECO 00023688 is a solid carbide turning insert in the WNMG432-M5 configuration, designed for precision metal-cutting operations on CNC and manual lathes. It carries a manufacturer grade of TP40 and features a multilayer CVD coating of TiC, TiCN, and TiN for wear resistance and thermal stability during interrupted and continuous cuts. The insert has a trigon shape with an 80-degree included angle, a 0.5 inch inscribed circle, a 0.0315 inch corner radius, and a negative rake geometry. With 6 available cutting edges, this insert delivers consistent performance across moderate to heavy turning applications on steel and stainless steel.

This insert is suited for general turning, facing, and boring operations in production and job-shop environments. It targets primary workpiece materials classified as P-grade steels and M-grade stainless steels, corresponding to ISO material codes P and M and material grades P40, M35, and M40. The M5 chip breaker geometry and chamfered-and-honed cutting edge style make it appropriate for medium-duty cuts where chip control and edge stability are priorities. Licensed machinists and CNC operators working in automotive, aerospace, and general fabrication applications will find this insert applicable to a wide range of roughing and semi-finishing lathe operations.

Key Features

• WNMG432-M5 trigon insert with 80-degree included angle and negative rake for rigid, stable cutting
• Multilayer CVD coating: TiC, TiCN, TiN for extended tool life on steel and stainless steel
• M5 chip breaker geometry designed for medium-duty turning and effective chip evacuation
• 6 indexable cutting edges per insert for cost-effective tooling management
• Chamfered and honed cutting edge style balances edge strength and surface finish
• Compatible with clamp, pin, and lever-lock insert holding methods

Compatibility

Designed for use in WNMG-style insert toolholders that accept a 0.5 inch inscribed circle trigon insert with clamp, pin, or lever-lock holding. Suitable for toolholders conforming to ANSI and ISO standards for WNMG insert geometry. Verify toolholder pocket dimensions and clamping style before installation.

Installation Notes

Installation is performed by qualified machinists or CNC operators following standard indexable insert procedures. Power down and lock out the machine before indexing or replacing the insert. Seat the insert fully in the toolholder pocket and confirm the clamping mechanism is secured to the toolholder manufacturer's specification before resuming operation. Inspect the cutting edge and chip breaker for damage at each index.
