Sandvik Coromant 7860511 Turning Insert TCMX32.52-WM 4415

Product Description

The SANDVIK COROMANT 7860511 is a solid carbide turning insert in the CoroTurn 107 series, designed for precision external turning operations on CNC lathes and turning centers. The insert carries grade 4415 with a multilayer CVD coating of Al2O3, TiN, and TiCN, providing thermal resistance and wear protection during continuous cuts. It features a triangular shape with a 60-degree included angle, a 3/8-inch inscribed circle, and a 0.0313-inch corner radius. The WM chip breaker geometry is engineered for steel and cast iron machining. Installed by machinists and CNC operators in production and job-shop environments, this insert suits medium to semi-finish turning passes.

This insert is suited for primary use on steel workpieces (ISO material group P) and secondary use on cast iron (ISO material group K). The TCMX style with clearance code C and tolerance code M fits standard TCMX-compatible toolholders that use clamp or screw holding methods. The neutral hand orientation allows use in both conventional and back-turning setups. It fits within the CoroTurn 107 toolholder family. ISO code for this insert is TCMX 16 T3 08-WM 4415.

Key Features

Compatibility

Designed for use with TCMX-compatible turning toolholders that accept clamp or screw clamping methods, within the SANDVIK COROMANT CoroTurn 107 toolholder series. ISO code TCMX 16 T3 08-WM 4415 identifies the exact insert seat geometry required.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and seating tool specified by the toolholder manufacturer when tightening the clamping screw to avoid insert cracking. Inspect the insert pocket and clamping mechanism for wear or debris before seating a new insert.
