Seco 00054165 WNMP431MF1 CP200 Carbide Turning Insert

Product Description

The SECO 00054165 is a solid carbide turning insert in the WNMP431MF1 geometry, manufacturer grade CP200, with a multilayer PVD TiAlN and TiN coating. It features an 80-degree trigon (W-shape) insert design with a 0.5000 inch inscribed circle, a 0.0157 inch corner radius, and a 0.1874 inch insert thickness. The MF1 chip breaker is optimized for finishing operations on stainless steel, superalloys, and titanium. Six cutting edges per insert, a neutral hand orientation, and negative rake geometry make this insert a high-value option for precision metal-cutting applications. Licensed machinists and CNC operators install this insert in compatible toolholders for boring, facing, and turning operations.

This insert is suited for finishing cuts on stainless steel and superalloys including titanium, with secondary application on steel and cast iron. It carries ISO material grade codes M01, M10, M20, S10, and S20, indicating high wear resistance across stainless and special alloy workpieces with moderate toughness range. The MF1 chip breaker geometry is designed for light finishing passes where controlled chip formation and surface finish are the primary goals. It is a multi-use insert applicable to boring, facing, and turning operations on CNC lathes and machining centers.

Key Features

• Solid carbide substrate with multilayer PVD TiAlN and TiN coating for high wear resistance on difficult materials
• MF1 chip breaker geometry optimized for finishing operations on stainless steel and superalloys
• 80-degree trigon insert shape (WNMP) with negative rake and negative side clearance for rigid, stable cutting
• Six usable cutting edges per insert reducing per-edge tooling cost
• Neutral hand orientation compatible with a wide range of standard WNMP toolholders
• Compatible holding methods include clamp, pin, and lever lock styles

Compatibility

Designed for use in WNMP-series toolholders accepting 431 size code inserts with clamp, pin, or lever lock holding methods. ANSI insert code WNMP431 and ISO insert code WNMP080404 (ISO code WNMG080404-MF1) define the fitment standard. Verify toolholder pocket geometry and clamping style before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque wrench per the toolholder manufacturer specification for the clamping screw — do not overtighten by hand. Inspect the insert seat and clamping surfaces for chips or debris before securing the insert to ensure proper seating and cutting-edge alignment.
