Seco 00072242 Turning Insert DNMP432MF1 CP200 Carbide

Product Description

The SECO 00072242 is a solid carbide turning insert in the DNMP-MF1 series, designed for precision metal cutting in demanding machining applications. The insert features a 55-degree diamond shape with a 0.5-inch inscribed circle and a 1/32-inch (0.0315 inch) corner radius. It carries a CP200 manufacturer grade with a multilayer PVD-applied TiAlN and TiN coating, delivering wear resistance and thermal stability at the cutting edge. The MF1 chip breaker geometry and honed cutting edge style are optimized for controlled chip formation during finish and semi-finish turning. This insert is used by machinists and CNC operators running production or job-shop turning operations.

This insert is suited for turning, facing, boring, and back turning operations. Its primary workpiece materials are stainless steel and superalloys and titanium (ISO material groups M and S). It also performs in secondary applications on steel and cast iron (ISO groups P and K). The DNMP-MF1 series targets applications where precise chip control and surface finish quality are critical, particularly in aerospace, medical, and energy sector component machining. The insert follows ANSI and ISO standards and carries the ISO code DNMG150408-MF1 and industry standard number DNMP432-MF1.

Key Features

• CP200 grade with multilayer PVD TiAlN and TiN coating for extended tool life on difficult-to-machine alloys
• MF1 chip breaker geometry optimized for finish to semi-finish turning on stainless steel, superalloys, and titanium
• 55-degree diamond insert shape with 0.5-inch inscribed circle and negative rake for stable cutting
• Honed cutting edge style reduces edge chipping on tough workpiece materials
• Four cutting edges per insert with neutral hand orientation for versatile setup
• Compatible with clamp, pin, and lever lock insert holding methods
• Multi-use application support: turning, facing, boring, and back turning

Compatibility

Designed as an OEM-style replacement and direct-fit insert for toolholders accepting DNMP-style inserts with a 0.5-inch inscribed circle, 3/16-inch insert thickness, and clamp, pin, or lever lock clamping. Conforms to ANSI and ISO standards; ISO code DNMG150408-MF1 and industry standard number DNMP432-MF1 apply for cross-reference purposes.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket before engaging the clamping mechanism. Inspect the pocket and clamping components for wear or debris before installation to ensure proper seating and cutting-edge repeatability.
