Seco 03275986 Turning Insert CNMP431-MF1 TM1501 Carbide

Product Description

The SECO 03275986 is a solid carbide turning insert in the CNMP431-MF1 series, grade TM1501, designed for precision metal cutting on CNC lathes and turning centers. It features an 80-degree diamond shape with a 0.5 inch inscribed circle, a 1/64 inch (0.0157 inch) corner radius, and a neutral hand orientation. The insert carries a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, engineered to extend tool life and maintain edge integrity under the thermal and mechanical demands of stainless steel and steel turning operations. Four cutting edges are available per insert, improving cost-per-edge efficiency in production environments.

This insert is suited for general turning, facing, and boring operations on stainless steel (ISO material code M) and steel (ISO material code P). It fits into toolholders accepting CNMP-style inserts with clamp, pin, or lever-lock holding methods. The MF1 chip breaker geometry is optimized for medium finishing passes, making this insert appropriate for shops running close-tolerance work on stainless alloys, carbon steels, and similar materials. It conforms to both ANSI and ISO standards, with the equivalent ISO designation CNMG120404-MF1.

Key Features

• CVD Duratomic coating (TiCN, Al2O3, Cr) for thermal resistance and extended tool life on stainless and steel
• 80-degree diamond insert shape with negative rake angle for strong, stable cutting geometry
• MF1 chip breaker geometry tuned for medium finishing on stainless steel and steel workpieces
• Four usable cutting edges per insert for improved cost efficiency
• Compatible with clamp, pin, and lever-lock toolholder systems
• Meets ANSI and ISO standards; ISO equivalent CNMG120404-MF1

Compatibility

Designed for use in CNMP-style toolholders accepting clamp, pin, or lever-lock insert retention. Suitable for turning, facing, and boring applications on stainless steel and steel workpieces. Multi-use tool rated for boring, facing, and turning operations.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC or manual turning equipment. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert. Inspect the insert pocket and seating surface for debris or damage before each index to ensure proper contact and edge repeatability.
