Sandvik Coromant 5726057 Turning Insert Carbide Diamond 80

Product Description

The SANDVIK COROMANT 5726057 is a solid carbide turning insert in the CNMX style, designed for high-performance metal cutting in demanding applications involving superalloys and titanium. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability at the cutting edge. The insert features an 80-degree diamond shape, a neutral hand orientation, and an SM chip breaker geometry suited for finishing and semi-finishing operations. With a 0.5000-inch inscribed circle and a 0.0315-inch corner radius, it provides precise chip control in difficult-to-machine materials. This insert is part of the Sandvik T-Max P series and is installed by machinist professionals in CNC turning centers.

This insert is engineered for turning superalloys and titanium workpieces where cutting-edge durability and chip evacuation are critical. The SM chip breaker geometry supports controlled chip flow at moderate to light depths of cut and feed rates typical in aerospace and energy sector component machining. The CNMX style with a clamp and pin holding method ensures rigid seating in compatible toolholders, minimizing vibration and insert movement during cuts. It is suited for use on CNC lathes and turning centers running ISO material group S workpieces.

Compatibility

Designed for use with CNMX-style toolholders that accept a 0.5000-inch inscribed circle insert with a 0.2030-inch hole diameter. Primary workpiece materials are superalloys and titanium (ISO material group S). ISO designation: CNMX 12 04 A2-SM S05F.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the CNC turning center before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware to seat the insert; do not over-tighten the clamping screw or pin. Verify insert seating and edge condition before resuming cutting operations.
