Seco 00000186 Turning Insert VNGM331F-MF1 CP500 Carbide

Product Description

The SECO 00000186 is a solid carbide turning insert designed for precision metal cutting in demanding machining environments. Manufactured to VNGM331F-MF1 industry standard, this insert features a 35-degree diamond shape with a negative rake angle and a 3/8-inch inscribed circle. It carries a CP500 manufacturer grade with a multilayer PVD-applied TiAlN and TiN coating for extended tool life and heat resistance. The MF1 chip breaker geometry and sharp cutting edge style make it well-suited for finishing and medium cutting passes. Two cutting edges per insert maximize value across applications.

This insert is primarily engineered for machining stainless steel and is also rated for steel, cast iron, super-alloys, and titanium. It supports back turning, facing, profiling, and turning operations, making it a versatile choice for shops running multi-operation programs. The neutral hand orientation allows straightforward setup in standard insert toolholders. Holding methods include clamp, pin, and lever lock configurations. It conforms to both ANSI and ISO standards, with an ISO code of VNGM160404-MF1 for cross-referencing in tooling catalogs.

Compatibility

Designed for use with VNGM-style insert toolholders that accept a 3/8-inch inscribed circle, 3/16-inch thick diamond insert with clamp, pin, or lever lock holding. Primary workpiece material is stainless steel (ISO material code M); secondary materials include steel (P), cast iron (K), and super-alloys and titanium (S). Material grades M10, M20, and M30 apply.

Installation Notes

Installation is performed by qualified machinists or tooling technicians following standard insert seating procedures. Power down and lock out the spindle before changing inserts. Ensure the insert pocket and seating surface are clean and free of chips before securing the insert. Follow the toolholder manufacturer's clamping torque specifications for the applicable holding method.
