Seco 02960840 Turning Insert CCMT431-M3 TP1501 Carbide

Product Description

The SECO 02960840 is a CCMT431-M3 series solid carbide turning insert designed for precision metal removal in CNC and manual lathe applications. It features an 80-degree diamond (rhombic) insert shape with a 1/2-inch inscribed circle, a 3/16-inch thickness, and a 1/64-inch (0.0157-inch) corner radius. The insert carries a TP1501 grade designation with a multilayer CVD Duratomic coating — TiCN, Al2O3, and Cr — engineered to deliver high wear resistance with moderate toughness. Licensed machinists and CNC operators install this insert for finishing and medium machining operations where consistent tool life and surface finish are the primary targets.

This insert is suited for turning, facing, and boring operations on steel and cast iron workpieces. Its P10/P20 material grade classification places it in the high-to-moderate wear-resistance range for steel (P) and cast iron (K) applications, with secondary suitability for hard materials (H). The M3 chip breaker geometry supports both finishing and medium machining pass depths, making it a practical choice for shops running varied part programs without swapping insert geometry between operations. It is screw-held and compatible with standard CCMT-style toolholders.

Key Features

• 80-degree diamond (rhombic) insert shape with positive rake and positive side clearance for reduced cutting forces
• Multilayer CVD Duratomic coating — TiCN, Al2O3, Cr — for high wear resistance on steel and cast iron
• M3 chip breaker geometry supports finishing and medium machining in a single insert style
• 2 cutting edges with chamfered and honed cutting edge style for edge stability
• Maximum depth of cut of 0.4921 inches with a 0.5000-inch inscribed circle for broad material engagement
• Conforms to ANSI (CCMT431) and ISO (CCMT120404-M3) standards for broad toolholder compatibility

Compatibility

Designed for use in standard CCMT-style screw-clamp toolholders conforming to ANSI and ISO insert seating specifications. Suitable for boring, facing, and turning operations on steel and cast iron workpieces. Multi-use application across CNC and manual turning centers.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing the insert. Use the appropriate torque driver for the clamping screw — do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper contact and edge alignment.
