Seco 02960021 Turning Insert DNMG432-FF2 TP1501 Carbide

Product Description

The SECO 02960021 is a solid carbide turning insert in the DNMG432-FF2 series, designed for precision material removal on CNC lathes and turning centers. It features a 55-degree diamond shape with a negative rake geometry and a honed cutting edge for consistent, controlled chip formation. The TP1501 grade uses a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — that delivers thermal stability and wear resistance during interrupted and continuous cuts. With four usable cutting edges and a 0.5 inch inscribed circle, this insert offers extended tool life in high-volume production environments. It is installed by machinists and CNC operators working in job shop and production turning applications.

This insert is suited for turning, facing, back turning, and boring operations on steel as its primary workpiece material, and cast iron and hard materials as secondary targets. The FF2 chip breaker geometry is optimized for finishing and light roughing passes where chip control is critical. It conforms to both ANSI and ISO standards, with the ISO code DNMG150408-FF2, making it a direct fit for standard DNMG-style toolholders that use clamp, pin, or lever lock holding methods. Typical applications include shaft turning, bore finishing, and face operations on medium-to-hard ferrous components in material grades P10 and P20.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for thermal and abrasion resistance
• 55-degree diamond insert shape with negative rake and honed cutting edge
• FF2 chip breaker for controlled chip formation in finishing and light roughing
• Four cutting edges per insert for extended tool life and cost efficiency
• Compatible with clamp, pin, and lever lock DNMG toolholders
• Multi-use capable: turning, facing, back turning, and boring

Compatibility

Designed for use in standard DNMG-style toolholders that accept clamp, pin, or lever lock insert holding methods. Conforms to ANSI and ISO standards per industry standard number DNMG432-FF2 and ISO code DNMG150408-FF2. Primary workpiece material is steel (P code); secondary workpiece materials are cast iron and hard materials (K and H codes).

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or indexing the insert. Use the appropriate torque driver for the clamp or lever lock screw — refer to the toolholder manufacturer specifications. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper insert contact and prevent premature edge failure.
