Seco 02960916 Turning Insert DCMT32.52-M3 TP2501 Carbide

Product Description

The SECO 02960916 is a solid carbide turning insert in the DCMT-M3 series, designed for precision metal cutting in CNC and manual turning applications. It features a 55-degree diamond shape with a neutral hand orientation and carries the TP2501 manufacturer grade with a Duratomic CVD multilayer coating — TiCN, Al2O3, and Cr — engineered for extended tool life and thermal resistance. The inscribed circle measures 0.375 inches with a corner radius of 0.0315 inches. With two cutting edges and a chamfered and honed cutting edge style, this insert delivers consistent performance in medium to roughing steel applications. Licensed machinists and CNC operators install this insert as a direct screw-held replacement in compatible DCMT toolholders.

This insert is suited for turning, facing, boring, and back turning operations on steel, stainless steel, and cast iron workpieces. It falls within ISO material grade classifications P10, P20, P30, and P35, making it well matched to general-purpose steel turning at moderate to heavy material removal rates. The M3 chip breaker geometry is optimized for controlled chip formation across these material families. It complies with both ANSI and ISO standards and carries the ISO code DCMT11T308-M3 alongside the industry standard number DCMT32.52-M3.

Key Features

• Duratomic CVD coating: TiCN, Al2O3, and Cr layers for wear and thermal resistance
• 55-degree diamond insert shape with positive rake for reduced cutting forces
• M3 chip breaker geometry for controlled chip evacuation on steel and stainless
• Two cutting edges for extended usable life per insert
• Screw-held mounting with 0.1772-inch hole diameter for secure toolholder retention
• Multi-use capability: turning, facing, boring, and back turning in a single insert

Compatibility

Designed for use in DCMT-style screw-clamp toolholders conforming to ANSI and ISO DCMT11T308 specifications. Primary workpiece material is steel (ISO P); secondary materials include stainless steel (ISO M) and cast iron (ISO K). ISO code DCMT11T308-M3 and industry standard number DCMT32.52-M3 apply.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the correct Torx or hex key. Inspect the insert pocket and locating surfaces for chips or debris before seating to avoid seating errors that can damage the toolholder or compromise dimensional accuracy.
