Seco 02960740 WNMG433-MF5 TP2501 Turning Insert Carbide

Product Description

The SECO 02960740 is a WNMG433-MF5 series indexable turning insert designed for high-productivity metal cutting in steel, stainless steel, and cast iron applications. It is manufactured from solid carbide with a CVD-applied Duratomic multilayer coating consisting of TiCN, Al2O3, and Cr layers. The TP2501 grade places this insert in the P10-P35 material grade range, making it well suited for continuous to moderately interrupted cuts on ferrous workpieces. The MF5 chip breaker geometry features a chamfered and honed cutting edge with negative rake, providing controlled chip formation during finishing and light roughing passes. With 6 available cutting edges per insert and compatibility with clamp, pin, and lever-lock toolholding systems, this insert delivers consistent performance across tooling setups.

This insert is intended for use on CNC lathes and turning centers in production machining environments. The WNMG trigon shape with an 80-degree included angle and neutral hand orientation makes it appropriate for boring, facing, and turning operations. The MF5 chip breaker geometry is optimized for steel and stainless steel finishing at moderate depths of cut. The insert is sold individually but requires a minimum order quantity of 10 units per order. It conforms to both ANSI and ISO standards, carrying the ISO designation WNMG080412-MF5 for cross-reference purposes.

Key Features

• CVD Duratomic multilayer coating: TiCN, Al2O3, and Cr layers for wear and crater resistance
• TP2501 grade covers P10 through P35 material grades for steel and stainless steel applications
• MF5 chip breaker with chamfered and honed edge for controlled chip formation in finishing passes
• 6 cutting edges per insert for extended tooling economy
• Compatible with clamp, pin, and lever-lock toolholding systems
• Negative rake, neutral hand; suitable for boring, facing, and turning operations

Compatibility

Designed for use in WNMG-series toolholders that accept a W-shape (80-degree trigon) insert with an inscribed circle of 0.5000 inches, a 3/16-inch insert thickness, and a hole diameter of approximately 0.2028 inches. Compatible toolholding methods include clamp, pin, and lever-lock systems conforming to ANSI and ISO WNMG080412 standards.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and all energy sources locked out before indexing or replacing inserts. Use the appropriate torque wrench and toolholder hardware specified by the toolholder manufacturer when seating the insert to avoid edge chipping or clamp distortion. Do not exceed the maximum depth of cut of 0.1063 inches for the cutting geometry to perform within design parameters.
