Sandvik Coromant 8020972 Rcmt 12 04 00 4415 Turning Insert

Product Description

The SANDVIK COROMANT 8020972 is a round turning insert manufactured to the RCMT 12 04 00 4415 ISO designation. It is made from solid carbide and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted turning operations. The insert carries a 0.5 inch inscribed circle, a neutral hand orientation, and a chip breaker designation of PR. It is designed for use in external and internal turning applications and is installed by machinists and CNC lathe operators in production and job-shop environments.

This insert is suited for turning steel workpieces, with a primary workpiece material classification of steel and a secondary material code of K. The RCMT (INCH) series configuration uses a round insert shape with clamp and screw holding methods and a clearance code of C with tolerance code M. Typical applications include finish and semi-finish turning of steel components where consistent edge life and surface finish are required. The PR chip breaker geometry supports chip control across a range of depths of cut and feed rates common in steel turning.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear and heat resistance
• Round insert shape (code R) with 0.5 inch inscribed circle
• Manufacturer grade 4415 optimized for steel turning
• Neutral hand orientation for flexible toolholder compatibility
• PR chip breaker geometry for controlled chip evacuation
• Clamp and screw holding method for secure seating under cutting loads

Compatibility

Designed as an OEM-style replacement insert for RCMT-series toolholders accepting a round insert with a 0.5 inch inscribed circle, clearance code C, and tolerance code M per ANSI and ISO insert standards.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before replacing inserts. Seat the insert fully in the pocket and verify clamp and screw torque using the toolholder manufacturer's specifications. Inspect the insert pocket for wear or debris before installing a new insert, as a damaged pocket can cause premature edge failure or dimensional error.
