Seco 02960443 TNMG431-M5 TP2501 Carbide Turning Insert

Product Description

The SECO 02960443 is a solid carbide triangular turning insert in the TNMG-M5 series, designed for precision metal removal on CNC lathes and turning centers. It carries the TP2501 manufacturer grade with a CVD-applied Duratomic multilayer coating consisting of TiCN, Al2O3, and Cr for extended tool life in interrupted and continuous cuts. The insert features a neutral hand orientation, a chamfered and honed cutting edge style, and a 0-degree relief angle (clearance code N). With six available cutting edges per insert and an M5 chip breaker geometry, this insert delivers controlled chip flow across a range of feed rates and depth-of-cut conditions. It conforms to both ANSI and ISO standards under ISO code TNMG220404-M5.

This insert is suited for machining steel as its primary workpiece material (ISO material code P), with secondary suitability for stainless steel (M) and cast iron (K). Applicable material grades span P10, P20, P30, and P35. It supports multiple operations including turning, facing, boring, and back turning, making it appropriate for general-purpose production turning in job shop and production environments. Licensed machinists and CNC operators working in industrial, aerospace, automotive, and general manufacturing settings are the typical end users. The insert is sold individually per package with a minimum order quantity of 10 units.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for high wear resistance and thermal stability
• Six cutting edges per insert for maximum economy per unit cost
• M5 chip breaker geometry for reliable chip control across steel and stainless steel applications
• Chamfered and honed cutting edge style reduces entry shock and extends edge life
• Neutral insert hand allows use on both left-hand and right-hand toolholders
• Compatible with clamp, pin, and lever lock insert holding methods

Compatibility

Designed for use in TNMG-series toolholders that accept a triangular insert with a 0.5-inch inscribed circle, 0-degree relief (clearance code N), and tolerance code M. Suitable for clamp, pin, and lever lock clamping systems. Conforms to ANSI and ISO TNMG220404-M5 dimensional standards.

Installation Notes

Installation is performed by qualified CNC machinists or tool-room personnel. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware to seat the insert securely in the toolholder pocket — do not over-tighten by hand. Inspect the insert pocket and seating surfaces for chips or debris before installing a new edge.
