Seco 02786785 Turning Insert CNMG430.5-FF2 CP500 Carbide

Product Description

The SECO 02786785 is a CNMG-style indexable turning insert in manufacturer grade CP500, designed for precision metal cutting in CNC turning applications. The insert features a multilayer PVD TiAlN and TiN coating applied over a solid carbide substrate, providing wear resistance and thermal stability in demanding cutting environments. It carries an 80-degree diamond shape, a 0.5-inch inscribed circle, a corner radius of approximately 0.008 inches, and an insert thickness of 0.187 inches. With four cutting edges and a neutral hand orientation, this insert suits high-volume production turning on CNC lathes and turning centers. Licensed machinists and tooling specialists are the primary users.

This insert is rated for primary use on stainless steel workpiece material (ISO material code M) and is secondarily suited for steel, cast iron, super-alloys, and titanium (ISO codes P, K, and S). Material grades M10, M20, and M30 apply. The FF2 chip breaker geometry and honed cutting edge style make it appropriate for a range of operations including boring, facing, and turning. It conforms to both ANSI and ISO standards and carries ISO designation CNMG120402-FF2.

Key Features

• CP500 grade with multilayer PVD TiAlN and TiN coating for extended tool life on stainless steel and steel
• 80-degree diamond insert shape (shape code C) with negative rake for strong cutting edge support
• FF2 chip breaker geometry suited for boring, facing, and turning operations
• Four usable cutting edges per insert, maximizing cost-per-edge value
• Compatible with clamp, pin, and lever lock insert holding methods
• Honed cutting edge style reduces microchipping on difficult workpiece materials

Compatibility

Designed as an OEM-style replacement or direct equivalent for toolholders accepting CNMG 430.5 inserts with clamp, pin, or lever lock holding methods per ANSI and ISO standards. Industry standard number CNMG430.5-FF2; ISO code CNMG120402-FF2.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be fully stopped and the turret locked before changing inserts. Use the appropriate torque wrench and insert screw or clamping hardware specified by the toolholder manufacturer. Inspect the toolholder pocket seat for damage or debris before seating a new insert, as a contaminated or worn pocket will affect cutting edge geometry and tool life.
