Seco 03275993 Turning Insert CNMG432-M5 TM2501 Carbide

Product Description

The SECO 03275993 is a CNMG432-M5 indexable turning insert manufactured from solid carbide with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr. It features an 80-degree diamond insert shape, a neutral hand orientation, a 0.5-inch inscribed circle, and a corner radius of 0.0315 inches. With four cutting edges and a chamfered and honed cutting edge style, this insert is designed for productive turning, facing, and boring operations. Licensed machinists and CNC lathe operators working in metalworking environments select this insert for its combination of edge toughness and wear resistance on demanding workpiece materials.

This insert is suited for machining stainless steel as its primary workpiece material, with steel as a secondary material application. It carries material grades M25, M30, and M35, making it appropriate for medium to roughing cuts in general turning operations. The M5 chip breaker geometry supports controlled chip formation across a range of feed rates and depths of cut. Typical installation contexts include production turning on CNC lathes in job shops and manufacturing facilities where consistent insert performance is required across multiple tool paths including boring, facing, and external turning.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for wear resistance on stainless steel and steel
• 80-degree diamond insert shape with negative rake and 0-degree relief angle for strong cutting edge
• M5 chip breaker geometry supports boring, facing, and turning applications
• Four cutting edges per insert for extended tool life and lower cost per edge
• Chamfered and honed cutting edge style for improved edge strength and chipping resistance
• Compatible with clamp, pin, and lever lock insert holding methods

Compatibility

Designed for use in toolholders and boring bars that accept CNMG432 (ISO: CNMG120408) style inserts with clamp, pin, or lever lock holding methods. Meets ANSI and ISO standards for CNMG series inserts.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and all axes at rest before indexing or replacing the insert. Ensure the insert pocket and seating surfaces are clean and free of chips before seating the insert. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer. Follow shop safety protocols and machine guarding requirements throughout the insert change process.
