Seco 02956350 VNMG331-FF2 TP2501 Turning Insert Carbide

Product Description

The SECO 02956350 is a multi-tipped solid carbide turning insert in the VNMG331-FF2 series, designed for precision turning operations on CNC and manual lathes. It features a 35-degree diamond insert shape with a neutral hand orientation and a honed cutting edge style. The TP2501 grade uses a CVD-applied Duratomic multilayer coating (TiCN, Al2O3, and Cr) to deliver thermal and wear resistance across a broad range of cut depths. With four cutting edges per insert and a 3/8-inch inscribed circle, this insert suits production environments where consistent tool life and repeatable finish quality are required. Licensed machinists and CNC operators install and index this insert as part of routine tooling maintenance.

This insert is suited for steel as its primary workpiece material (ISO P classification) and is rated for use on stainless steel and cast iron as secondary materials (ISO M and K classifications). Typical applications include back turning, facing, profiling, and general turning. The FF2 chip breaker geometry is well-suited for light to medium depth-of-cut passes where controlled chip flow and surface finish matter. It conforms to ANSI and ISO standards under ISO code VNMG160404-FF2 and industry standard number VNMG331-FF2. Material grades P10, P20, P30, and P35 apply.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended tool life in steel and stainless cutting
• 4 indexable cutting edges per insert for maximum value in high-volume turning operations
• FF2 chip breaker geometry optimized for back turning, facing, profiling, and turning
• 35-degree diamond insert shape (VNMG) with negative rake and 0-degree relief angle (clearance code N)
• Honed cutting edge style reduces micro-chipping on entry and exit
• Clamp, pin, and lever lock holding methods supported for broad toolholder compatibility

Compatibility

Designed as an OEM-style replacement and standard production insert for VNMG toolholders conforming to ANSI and ISO VNMG160404 specifications. Compatible with clamp, pin, and lever lock style toolholders accepting a 0.150-inch hole diameter. Verify toolholder designation before ordering to confirm insert pocket geometry match.

Installation Notes

Indexing and replacement of turning inserts is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before accessing the turret or toolholder. Use the appropriate torque wrench or driver for the clamping screw to avoid cracking the carbide insert body — refer to the toolholder manufacturer specification for fastener torque. Inspect the insert pocket seat and shim for wear or damage before seating a new insert.
