Seco 00054166 Turning Insert WNMP432-MF1 CP200 Carbide

Product Description

The SECO 00054166 is a solid carbide trigon turning insert in the WNMP-MF1 series, manufactured to ANSI and ISO standards under the industry designation WNMP432-MF1 with ISO code WNMG080408-MF1. It carries a multilayer PVD TiAlN and TiN coating in manufacturer grade CP200, engineered to handle the demands of stainless steel and superalloy and titanium machining. The insert features a 0.5000-inch inscribed circle, a 0.0315-inch corner radius, and an 80-degree included angle with a negative rake geometry and honed cutting edge style. It is a neutral-hand insert with six available cutting edges, making it a cost-effective option for production turning operations.

This insert is suited for facing, boring, and turning operations on stainless steel, superalloys, and titanium as primary workpiece materials, with secondary capability on steel and cast iron. The MF1 chip breaker geometry is designed for finishing to medium cutting passes where chip control is critical. It fits toolholders using clamp, pin, or lever lock holding methods and is applicable in both CNC and manual lathe setups in precision machining, aerospace component work, and general metalworking environments.

Key Features

• Multilayer PVD TiAlN and TiN coating in CP200 grade for heat and wear resistance in difficult-to-machine alloys
• MF1 chip breaker geometry optimized for finishing and light-to-medium turning on stainless steel and superalloys
• Six cutting edges per insert for extended tool life and reduced cost per edge
• Neutral hand insert compatible with clamp, pin, and lever lock toolholder styles
• Honed cutting edge style reduces micro-chipping on tough workpiece materials
• Conforms to ANSI and ISO insert standards for broad toolholder compatibility

Compatibility

Designed for use in WNMP-style toolholders that accept a 432 insert size with clamp, pin, or lever lock holding methods. Compatible with toolholder systems conforming to ANSI and ISO WNMG080408 insert seat specifications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and at rest before indexing or replacing the insert. Use the appropriate torque wrench and seating tool recommended by the toolholder manufacturer to avoid seat damage or insert cracking. Ensure the insert seat and pocket are clean and free of chips before seating. Follow shop safety protocols and toolholder manufacturer guidelines when handling carbide inserts.
