Seco 02787054 Vnmg 331-FF2 CP500 Turning Insert

Product Description

The SECO 02787054 is a solid carbide turning insert in the VNMG 331-FF2 series, designed for precision metal cutting on CNC and manual lathes. It carries a multilayer PVD TiAlN and TiN coating and the CP500 manufacturer grade, making it well-suited for stainless steel as the primary workpiece material. The 35-degree diamond insert shape (V code) provides a sharp, stable cutting geometry with a honed cutting edge style. The FF2 chip breaker controls chip flow across facing, profiling, back turning, and general turning operations. Machinist and CNC operators install this insert as a direct OEM-style replacement in compatible turning toolholders.

This insert is engineered for use in production and job-shop environments where stainless steel is the primary workpiece. It also performs on steel, cast iron, super-alloys, and titanium as secondary materials, covering ISO material groups M, P, K, and S. The FF2 chip breaker geometry handles light to medium cuts in facing, profiling, back turning, and turning applications. It is a neutral-hand insert, fitting standard VNMG-style toolholders used in both manual and CNC lathe setups. The ISO code VNMG160404-FF2 and industry standard number VNMG331-FF2 confirm direct cross-reference compatibility.

Key Features

• 4 cutting edges per insert for extended tooling value
• Honed cutting edge style reduces chipping risk on difficult-to-machine alloys
• Compatible insert holding methods: clamp, pin, and lever lock
• Meets ANSI and ISO standards; ISO code VNMG160404-FF2

Compatibility

Designed as an OEM-style replacement insert for VNMG-style turning toolholders. ISO designation VNMG160404-FF2 and industry standard number VNMG331-FF2 apply. Compatible holding methods include clamp, pin, and lever lock systems. Primary workpiece material is stainless steel (ISO code M); secondary workpiece materials include steel, cast iron, super-alloys, and titanium (ISO codes P, K, S).

Installation Notes

Installation is performed by machinists and CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert key for the toolholder clamping system to avoid seat damage or insert fracture. Inspect the insert pocket and shim seat for wear or debris before seating the new insert.
