Seco 03094162 WNMG331-MF2 TP3501 Turning Insert Carbide

Product Description

The SECO 03094162 is a WNMG331-MF2 series indexable turning insert designed for steel and stainless steel machining. It is manufactured from solid carbide and coated via CVD with a Duratomic TiCN, Al2O3, and Cr multilayer coating in manufacturer grade TP3501. The insert features an 80-degree trigon (W) shape with a negative rake angle, a 0-degree relief angle (clearance code N), and an MF2 chip breaker geometry with a chamfered and honed cutting edge. The 3/8-inch inscribed circle and 1/64-inch corner radius make this insert well suited for light-to-medium turning, facing, and boring operations on steel and stainless steel workpieces. It delivers 6 usable cutting edges per insert.

This insert is intended for use in CNC lathes and turning centers performing external turning, facing, and boring operations. Primary workpiece material is steel (ISO material code P), with a rated material grade range of P20, P30, and P40. Secondary application covers stainless steel (ISO material code M). The insert is compatible with toolholders that accept WNMG-style inserts using clamp, pin, or lever-lock holding methods. It conforms to both ANSI and ISO standards and carries ISO code WNMG060404-MF2. This insert is sold individually with a minimum order quantity of 10 units.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for wear resistance in steel and stainless applications
• MF2 chip breaker geometry with chamfered and honed cutting edge for controlled chip formation
• 6 cutting edges per insert for extended tool life and lower cost per edge
• Negative rake, 0-degree relief angle suits rigid setups and interrupted cuts in steel
• Compatible with clamp, pin, and lever-lock toolholder systems
• Meets ANSI and ISO standards; dual-designated WNMG331-MF2 (ANSI) and WNMG060404-MF2 (ISO)

Compatibility

Designed for use in WNMG-style indexable toolholders accepting clamp, pin, or lever-lock retention. Rated for steel workpieces in material grades P20, P30, and P40, and for stainless steel secondary applications. Suitable for turning, facing, and boring operations on CNC lathes and turning centers.

Installation Notes

Installation is performed by a machinist or toolroom technician using the appropriate torx or hex key for the toolholder clamping system. Power down and zero-energy-lock the machine before indexing or replacing inserts. Ensure the insert seat and pocket are clean and free of chips before seating the insert to prevent rocking or improper clamping. Follow the toolholder manufacturer's specified clamping torque for WNMG-style inserts.
