Sandvik Coromant 8020976 Turning Insert Rcmx 10 03 00 4415

Product Description

The SANDVIK COROMANT 8020976 is a round carbide turning insert in the RCMX series, ISO-coded RCMX 10 03 00 4415. It is designed for external and internal turning operations on CNC lathes and manual turning centers. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal protection during interrupted or continuous cuts. With a 0.3937-inch inscribed circle and a 0.1969-inch corner radius, it suits medium to roughing passes. Neutral hand orientation makes it suitable for both left-hand and right-hand toolholders. Machinists, CNC operators, and tool-room technicians working with cast iron and similar materials will find this insert appropriate for production turning environments.

The RCMX 10 03 00 4415 is intended for turning applications where a round insert profile is specified. The round shape distributes cutting forces evenly and extends tool life in intermittent cutting conditions. The 4415 grade and K-series secondary workpiece material code indicate suitability for cast iron machining. The clamp-and-screw holding method provides secure seating in compatible RCMX-style toolholders. This insert is used in job shops, production turning cells, and maintenance machining environments where consistent finish and edge stability are required across multiple passes.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection
• Round insert shape (Shape Code R) distributes cutting forces uniformly around the full edge
• 0.3937-inch inscribed circle and 0.1969-inch corner radius for medium-to-rough turning passes
• Neutral hand orientation compatible with both left-hand and right-hand toolholders
• Clamp and screw holding method ensures secure, repeatable insert seating
• Manufacturer grade 4415 with PR chip breaker geometry

Compatibility

Designed as a direct-fit replacement for RCMX-style toolholders accepting a round carbide turning insert with a 0.3937-inch inscribed circle, 7-degree relief angle, M-tolerance, and C-clearance code per ISO standard RCMX 10 03 00.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or CNC tooling technician with the machine spindle stopped and all axis motion disabled. Use the appropriate torx or hex key for the clamping screw specified by the toolholder manufacturer; do not overtighten, as this can fracture the insert. Inspect the toolholder pocket and seating surface for chips or debris before seating the insert. Handle carbide inserts carefully to avoid edge chipping prior to installation.
