Seco 02960431 Turning Insert TCMT32.51-M3 TP2501 Carbide

Product Description

The SECO 02960431 is a triangular solid carbide turning insert in the TCMT-M3 series, designed for precision metal cutting on CNC lathes and turning centers. It carries a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — that delivers wear resistance and thermal stability in demanding cutting conditions. The insert has a 3/8-inch (0.375 inch) inscribed circle, a 0.0157-inch corner radius, and an insert thickness of 0.1563 inches. With three usable cutting edges and a positive rake geometry, it is suited for moderate to high material removal rates. This part is sold individually with a minimum order quantity of 10 units.

This insert is intended for ferrous machining applications including back turning, boring, facing, and general turning. Its primary workpiece material is steel, with secondary suitability for stainless steel and cast iron. The M3 chip breaker geometry and chamfered-and-honed cutting edge style make it effective across a range of depths of cut up to 0.6102 inches. It fits standard TCMT-style toolholders that accept a screw-lock insert-holding method. Machinists working in job shop and production environments on P10 through P35 material grades will find this insert appropriate for light to medium roughing and finishing passes.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended tool life in steel cutting
• Triangular insert shape with 60-degree included angle and positive rake for reduced cutting forces
• Three cutting edges per insert for cost efficiency in high-volume turning operations
• M3 chip breaker suited for back turning, boring, facing, and turning applications
• Chamfered and honed cutting edge style for edge stability and surface finish consistency
• Meets ANSI and ISO standards; ISO code TCMT16T304-M3, industry standard number TCMT32.51-M3

Compatibility

Designed for use in TCMT-style screw-lock toolholders. Compatible with machining of steel (primary), stainless steel, and cast iron workpieces. Fits toolholder bores accommodating a 0.1772-inch hole diameter insert. Verify toolholder seating pocket matches the TCMT insert geometry before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and torque the clamping screw per the toolholder manufacturer specification. Inspect the seating pocket for chips or debris before installing a fresh edge, as an unseated insert can cause premature edge failure or workpiece damage.
