Sandvik Coromant 8020975 Rcmt Turning Insert Carbide

Product Description

The SANDVIK COROMANT 8020975 is a round carbide turning insert conforming to ISO designation RCMT 16 06 M0 4415. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, engineered to deliver high wear-resistance through moderate wear-resistance and toughness on steel workpieces. The insert measures 0.6299 inches inscribed circle diameter with a 0.315-inch corner radius and a 0.25-inch insert thickness. The neutral hand orientation and negative side clearance make it compatible with clamp and screw holding systems. Machinists and CNC lathe operators install this insert in turning applications requiring reliable performance across roughing and medium machining passes on steel.

This insert targets steel (ISO material code P) as its primary workpiece material, with cast iron (code K) as a secondary application. The PR chip breaker geometry is optimized for roughing and medium machining operations where chip control and edge stability under interrupted or continuous cuts are critical. It is suited to production turning environments in both shop and manufacturing settings where consistent tool life across multiple passes is a priority.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for high wear-resistance on steel
• Round insert shape (R) with 0.6299-inch inscribed circle for full-radius profiling
• PR chip breaker geometry rated for roughing and medium machining operations
• Negative side clearance with clamp and screw holding compatibility
• Grade 4415 formulated for steel (ISO P) primary and cast iron (ISO K) secondary workpiece materials
• Neutral hand orientation fits standard RCMT-style toolholders

Compatibility

Designed as an OEM-style replacement turning insert for RCMT-style toolholders accepting a 0.6299-inch inscribed circle, negative clearance, round geometry insert per ISO and ANSI code RCMT 16 06 M0.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or hex key specified for the toolholder clamping system and do not overtighten the clamping screw. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper contact and accurate tool-nose positioning.
