Seco 02960514 Turning Insert DNMU332-M5 TP1501 Carbide

Product Description

The SECO 02960514 is a solid carbide turning insert in the DNMU-M5 series, designed for precision metal cutting in CNC lathe and turning center applications. It carries the industry standard designation DNMU332-M5 and uses a TP1501 grade with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr for extended tool life in steel and cast iron. The insert features a 55-degree diamond shape, a negative rake angle, and a chamfered and honed cutting edge style. With four available cutting edges and a neutral hand orientation, it suits high-volume production environments where consistent edge performance matters. Licensed HVAC technicians do not install this part — it is specified by machinists and tooling engineers.

This insert is suited for steel (ISO P10, P20) as a primary workpiece material, with cast iron and hard materials as secondary targets. Multi-use applications include turning, facing, boring, and back turning. The M5 chip breaker geometry is engineered for medium-depth passes in these materials. It is held in compatible DNMU-style toolholders using clamp, pin, or lever-lock methods. This insert is sold individually with a minimum order quantity of 10 units per transaction.

Key Features

• CVD Duratomic coating (TiCN, Al2O3, Cr) for wear resistance in steel and cast iron
• 55-degree diamond insert shape with negative rake and 0 degrees relief angle
• M5 chip breaker geometry supports medium-cut turning, facing, boring, and back turning
• Four cutting edges per insert for extended cost-per-edge value
• Chamfered and honed cutting edge style reduces chipping on entry
• Compatible with clamp, pin, and lever-lock toolholder systems
• Meets ANSI and ISO standards; ISO code DNMU110408-M5

Compatibility

Designed for use in DNMU-style toolholders accepting a 3/8-inch inscribed circle, 55-degree diamond insert. Compatible with applications involving steel (ISO P code) and cast iron or hard materials (ISO K and H codes). Multi-use application types include turning, facing, boring, and back turning per supplier specification.

Installation Notes

Installation is performed by a machinist or tooling technician on a CNC or manual lathe. Power down and lock out the machine spindle before seating or replacing inserts. Ensure the toolholder pocket is clean and free of chips before clamping. Use the correct torque driver for the specified clamping method (clamp, pin, or lever lock) per the toolholder manufacturer instructions.
