Seco 02615934 Vnmg 332-MF4 TS2000 Carbide Turning Insert

Product Description

The SECO 02615934 is a VNMG 332-MF4 series indexable turning insert manufactured from solid carbide with a multilayer PVD TiAlN and TiN coating in the TS2000 grade. The insert features a 35-degree diamond shape (V shape code), a 3/8 inch inscribed circle, and a 1/32 inch corner radius. With 4 cutting edges, a negative rake geometry, and chamfered and honed cutting edge style, this insert is engineered for productive metal removal in demanding turning applications. The MF4 chip breaker geometry is optimized for finishing and semi-finishing operations on difficult-to-machine materials. Licensed machinists and CNC operators install this insert in compatible VNMG-style tool holders.

This insert is primarily rated for stainless steel (ISO material code M) and superalloys and titanium (ISO material code S), with secondary suitability for steel, cast iron, and hard materials (ISO codes P, K, H). Typical applications include back turning, facing, profiling, and general turning. The MF4 chip breaker geometry suits light to medium finishing cuts where consistent chip control and surface finish are critical. The ISO designation for this insert is VNMG160408-MF4, and the industry standard number is VNMG332-MF4. Maximum depth of cut reaches 0.5748 inches, making it capable across a range of finish and semi-finish passes.

• 4 cutting edges per insert for extended tool life and lower cost per edge
• Chamfered and honed cutting edge style reduces chipping and improves edge integrity
• Compatible with clamp, pin, and lever lock insert holding methods
• Meets ANSI and ISO standards; ISO designation VNMG160408-MF4

Compatibility

Designed for use in VNMG-style indexable turning tool holders that accept a 332 insert size with clamp, pin, or lever lock holding methods. ISO designation VNMG160408-MF4 and industry standard number VNMG332-MF4 can be used to cross-reference compatible holders. Verify holder specifications before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully and evenly in the pocket before tightening the clamping mechanism to the tool holder manufacturer's specified procedure. Inspect the insert pocket and seating surface for chips or debris prior to installation to avoid insert rocking or premature breakage.
