Seco 02956349 Turning Insert VNMG330.5-FF2 TP2501 Carbide

Product Description

The SECO 02956349 is a VNMG-series indexable turning insert designed for general-purpose metal cutting on CNC lathes and turning centers. It carries the TP2501 grade designation and features a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — engineered to extend tool life on steel and stainless steel applications. The insert has a 35-degree diamond shape (V), a neutral hand orientation, and a honed cutting edge style. With four usable cutting edges and a 0.0079-inch corner radius, it delivers consistent performance across a range of material removal rates. The FF2 chip breaker geometry targets finishing and semi-finishing cuts on ductile workpiece materials.

This insert is suited for external turning, facing, back turning, and profiling operations on steel (ISO P), stainless steel (ISO M), and cast iron (ISO K) workpieces. It fits standard VNMG toolholders that accept clamp, pin, or lever lock insert holding methods. Typical applications include production turning on manual and CNC lathes in automotive, general machining, and precision component shops. The TP2501 grade falls within material grades P10 through P35, making it appropriate for moderate to interrupted cuts on carbon and alloy steels. Sold individually; minimum order quantity is 10 pieces per transaction.

Key Features

• Duratomic CVD multilayer coating (TiCN, Al2O3, Cr) for extended wear resistance on steel and stainless
• FF2 chip breaker geometry optimized for finishing and semi-finishing passes
• Four cutting edges per insert for cost-effective indexing
• 35-degree diamond insert shape enables profiling and back turning in tight clearances
• Honed cutting edge reduces built-up edge on ductile materials
• Compatible with clamp, pin, and lever lock toolholder holding methods

Compatibility

Designed for VNMG-style toolholders that accept a 3/8-inch inscribed circle insert. Conforms to ANSI and ISO standards; ISO code VNMG160402-FF2. Compatible with ISO P (steel), ISO M (stainless steel), and ISO K (cast iron) workpiece materials.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is stopped and the turret is in a safe index position before seating or indexing the insert. Verify the toolholder pocket and clamping mechanism are clean and free of chips before installing; debris under the insert will cause premature edge failure. Follow the toolholder manufacturer torque guidance for the clamping screw — do not overtighten lever lock or pin clamp hardware.
