Sandvik Coromant 8019476 Turning Insert Rcmt Round Carbide

Product Description

The SANDVIK COROMANT 8019476 is a round carbide turning insert in the RCMT series, designed for precision metal turning operations on CNC lathes and turning centers. Manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, this insert delivers wear resistance and thermal stability under demanding cutting conditions. The ISO designation is RCMT 10 T3 M0 4425, featuring a 0.3937-inch inscribed circle diameter, a 0.1969-inch corner radius, and a neutral hand orientation. It is suited for machinists and CNC operators performing external and internal turning on steel workpieces.

This insert is intended for primary use on steel workpieces, with secondary application on materials corresponding to ISO material group K. The RCMT round insert shape provides a continuous cutting edge, making it well suited for profiling, contouring, and copy turning passes. The M0 chip breaker geometry supports a broad range of cutting parameters and depths of cut in general turning applications. Typical installation environments include production machine shops, job shops, and maintenance facilities running manual or CNC turning equipment.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on steel
• Round insert shape (code R) with continuous cutting edge for profiling and contouring
• 0.3937-inch inscribed circle and 0.1969-inch corner radius for precise fit to RCMT toolholders
• Neutral hand orientation for use in both left- and right-hand toolholder configurations
• M0 chip breaker geometry suitable for general-purpose turning across varied depths of cut
• Clamp and screw holding method compatible with standard RCMT insert seats

Compatibility

Designed as an OEM-style replacement turning insert for RCMT-style toolholders accepting a 10T3 round insert with a 0.3937-inch inscribed circle diameter and clamp or screw retention.

Installation Notes

Insert replacement and seating should be performed by a qualified machinist or CNC tooling technician with the machine fully powered down and the spindle locked. Inspect the toolholder pocket and clamping components for wear or debris before seating the new insert. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer's specification. Handle carbide inserts with care to avoid chipping the cutting edge during installation.
