Seco 02960091 WNMG432-M3 Turning Insert TP0501 Carbide

Product Description

The SECO 02960091 is a WNMG432-M3 series indexable turning insert designed for general-purpose metal removal on CNC and manual lathes. It features an 80-degree trigon (W-shape) geometry with a negative rake angle and a neutral hand orientation. The insert carries the TP0501 manufacturer grade and is coated via CVD with a TiCN, Al2O3, and Cr multilayer Duratomic coating system, delivering extended tool life in steel and cast iron applications. With a 0.5000-inch inscribed circle, a 0.0315-inch corner radius, and six available cutting edges per insert, the 02960091 offers reliable consistency across high-volume production runs. It is typically installed by machinists and toolroom technicians in turning centers and multi-axis lathes.

This insert is rated for boring, facing, and turning operations. Its primary workpiece material designation is Steel (ISO P-class), with Cast Iron (ISO K-class) as a secondary application. The M3 chip breaker geometry is suited for medium-depth passes and interrupted or continuous cuts in general steel turning. The insert conforms to both ANSI and ISO standards, with an ISO code of WNMG080408-M3 and an industry standard number of WNMG432-M3. Material grades P01 and P10 indicate suitability for finishing to light roughing cuts in ferrous materials.

Key Features

• CVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for thermal resistance and wear life in steel and cast iron
• Six cutting edges per insert reduces per-edge tooling cost in production environments
• M3 chip breaker geometry supports medium-cut boring, facing, and turning operations
• Chamfered and honed cutting edge style balances edge strength with surface finish quality
• Compatible with clamp, pin, and lever-lock insert holding methods for toolholder flexibility
• Meets ANSI and ISO standards; ISO code WNMG080408-M3 for cross-reference sourcing

Compatibility

Designed for use in WNMG-style toolholders that accept a 0.5000-inch inscribed circle insert with a 0.2028-inch hole diameter, using clamp, pin, or lever-lock holding methods. Primary workpiece materials are Steel (P-class) and Cast Iron (K-class) per ISO material classification. Multi-use application across boring, facing, and turning operations.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the machine in a fully stopped and locked-out state. Use the appropriate torque wrench and manufacturer-recommended seating hardware for the specific toolholder clamping method in use. Inspect the insert pocket and seating surface for chips or debris before seating a new edge. Never attempt to index or replace an insert while the spindle is powered or the turret is in motion.
