Product Description

The SANDVIK COROMANT 5730858 is a solid carbide turning insert in a DCMT style with a 55-degree diamond shape. It features a multilayer TiCN, Al2O3, and TiN coating applied over a carbide substrate, delivering wear resistance and thermal protection in a range of turning applications. The insert has a 3/8 inch inscribed circle, a 1/32 inch corner radius, and an overall length of 0.4263 inches. Chip control is handled by the PF chip breaker geometry. The manufacturer grade is 1515. This insert is installed by machinists and CNC lathe operators in production and job-shop environments.

This insert is suited for external and internal turning operations on lathes and turning centers. The 55-degree diamond shape and 7-degree relief angle make it well-matched to profiling and finishing passes. The PF chip breaker is designed for finishing to light interrupted cuts. The ISO code for this insert is DCMT 11 T3 08-PF 1515, which can assist with cross-referencing to toolholder systems and insert pockets designed around DCMT geometry. It is sold individually with a minimum order quantity of 10 units.
