Seco 02960040 Turning Insert VNMG330.5-FF2 TP1501 Carbide

Product Description

The SECO 02960040 is a solid carbide turning insert in the VNMG-FF2 series, designed for precision finishing operations on steel and cast iron workpieces. It carries the industry-standard designation VNMG330.5-FF2 and is manufactured to the TP1501 grade with a Duratomic CVD coating stack of TiCN, Al2O3, and Cr for high wear resistance. The insert features a 35-degree diamond (rhombic) shape, a 3/8 inch inscribed circle, and a corner radius of 0.0079 inches, making it well suited for light finishing passes where surface finish and dimensional control are priorities. Licensed machinists and CNC turning specialists install this insert in production and job-shop turning applications.

This insert is intended for use in CNC lathes and turning centers performing finishing, facing, profiling, and back turning operations. Its FF2 chip breaker geometry is optimized for finishing cuts on steel (ISO P) and cast iron (ISO K) materials, covering material grades P10 and P20. The negative rake, negative side clearance design provides robust edge support, and four available cutting edges maximize insert utilization. It is appropriate for both light-production and high-volume turning environments where consistent surface finish is required.

Key Features

• Duratomic CVD coating (TiCN, Al2O3, Cr) delivers high wear resistance across steel and cast iron grades
• FF2 chip breaker geometry engineered specifically for finishing operations
• Four cutting edges per insert for extended tooling economy
• 35-degree diamond insert shape enables access to tight workpiece profiles and shoulder work
• Compatible with clamp, pin, and lever-lock insert holding systems
• Conforms to ANSI and ISO standards; ANSI code VNMG330.5, ISO code VNMG160402

Compatibility

Designed for use in toolholders accepting VNMG-style inserts with a 3/8 inch inscribed circle and negative rake seating; compatible with clamp, pin, and lever-lock holding methods. Verify toolholder specification against ANSI insert code VNMG330.5 or ISO insert code VNMG160402 before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine powered down and in a locked-out state. Seat the insert fully against the toolholder pocket before tightening the clamping mechanism to the holder manufacturer's specified procedure. Inspect the cutting edge and chip breaker for damage before each use; do not use a chipped or cracked insert. Follow shop-specific tooling change procedures and applicable machine safety codes when handling carbide inserts.
