Seco 02615986 Turning Insert VNGP330.5-M1 TS2500 Carbide

Product Description

The SECO 02615986 is a solid carbide turning insert in the VNGP-M1 series, designed for high-performance metal cutting on CNC lathes and turning centers. It carries the TS2500 manufacturer grade with a multilayer PVD TiAlN/TiN coating, making it well suited for demanding cuts in superalloys and titanium where heat resistance and edge retention are critical. The 35-degree diamond (V) insert shape, neutral hand orientation, and M1 chip breaker geometry deliver sharp, controlled cutting across a range of operations. With four usable cutting edges per insert, the 02615986 offers extended tool life per unit. Licensed machinists and CNC operators typically specify this insert for production turning applications where workpiece material hardness and thermal load are primary concerns.

This insert is intended for back turning, facing, profiling, and general turning operations. Its primary workpiece material classification is superalloys and titanium (ISO code S), with secondary capability across steel, stainless steel, and cast iron (ISO codes P, M, and K). The VNGP330.5-M1 geometry and TS2500 grade make it a practical choice for aerospace, power generation, and precision manufacturing environments where tight tolerances and difficult-to-machine alloys are routine. The ISO equivalent designation is VNGG160402-M1.

Key Features

• TS2500 grade solid carbide construction with multilayer PVD TiAlN/TiN coating for heat and wear resistance
• 35-degree diamond (V) insert shape with sharp cutting edge style for clean entry into hard materials
• M1 chip breaker geometry optimized for superalloys, titanium, steel, stainless steel, and cast iron
• Four cutting edges per insert (multi-tipped) for extended usable tool life
• Neutral hand orientation compatible with clamp, pin, and lever-lock insert holding methods
• Meets ANSI and ISO standards; ISO equivalent VNGG160402-M1

Compatibility

Designed for use in VNGP-style turning toolholders that accept clamp, pin, or lever-lock holding methods. Compatible with toolholders rated for a 35-degree diamond (V) insert shape, clearance code N, tolerance code G, and a 3/8-inch inscribed circle. Suitable for back turning, facing, profiling, and turning operations on superalloys, titanium, steel, stainless steel, and cast iron workpieces.

Installation Notes

Installation is performed by qualified CNC machinists or tool-room technicians. Power down and lock out the machine spindle before seating or replacing inserts. Ensure the toolholder pocket and clamp surfaces are clean and free of chips before seating the insert, as debris under the insert affects cutting geometry and edge stability. Follow the toolholder manufacturer's clamping procedure for the specific holding method (clamp, pin, or lever lock) in use.
