Seco 02960550 WNMG332-M5 TP2501 Carbide Turning Insert

Product Description

The SECO 02960550 is a WNMG332-M5 indexable turning insert engineered for general and interrupted-cut turning on CNC lathes and boring bars. It features a solid carbide substrate with a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — designed for extended tool life in continuous and semi-interrupted cuts. The insert follows the WNMG (W-shape, trigon) geometry with an 80-degree included angle, a 0-degree relief angle (clearance code N), and an M-tolerance class for consistent seating. With six available cutting edges and an M5 chip breaker geometry, this insert is suited for medium roughing to semi-finishing operations across a broad range of depth-of-cut conditions. It is installed by machinists and CNC tooling technicians.

This insert is designed for primary use on steel (ISO P-class, material grades P10 through P35) and is rated for secondary use on stainless steel (ISO M-class) and cast iron (ISO K-class). Multi-use applications include turning, facing, and boring. The 0.0315-inch corner radius and chamfered-and-honed cutting edge style make it suitable for moderate surface finish requirements in production environments. It is compatible with WNMG-style insert pockets accepting clamp, pin, or lever-lock holding methods.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for thermal resistance and wear protection
• M5 chip breaker geometry supports turning, facing, and boring in medium-cut applications
• Six cutting edges per insert for extended insert economy
• Chamfered and honed cutting edge style reduces built-up edge on steel and stainless
• Negative rake, 0-degree relief angle provides strong edge geometry for interrupted cuts
• Compatible with clamp, pin, and lever-lock toolholding systems

Compatibility

Designed for use in WNMG-style insert pockets accepting the 332 insert size (0.375-inch inscribed circle, 0.1874-inch thickness). Holding method compatibility includes clamp, pin, and lever-lock systems. Industry standard number WNMG332-M5; ISO code WNMG060408-M5. Conforms to ANSI and ISO insert standards.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always index or replace inserts with the machine fully stopped and in a safe, locked-out state. Seat the insert fully into the pocket before tightening the clamping mechanism to the toolholder manufacturer's specified procedure. Inspect the insert pocket and clamping components for wear or debris before each insert change to ensure consistent seating and edge repeatability.
