Sandvik Coromant 7860495 Turning Insert 3/8 Inch Triangle

Product Description

The SANDVIK COROMANT 7860495 is a TCMT-style turning insert designed for external and internal turning operations on CNC lathes and turning centers. This triangular insert features a 60-degree included angle, a 3/8-inch inscribed circle, and a 0.0156-inch (0.40 mm) corner radius. It is manufactured from solid carbide and finished with a CVD-applied multilayer coating of Al2O3, TiCN, and TiN under manufacturer grade 4415. The PF chip breaker geometry is optimized for finishing passes. Machining professionals and CNC operators install this insert as part of the CoroTurn 107 system.

This insert is suited for finishing and light turning applications on steel as the primary workpiece material and cast iron as the secondary workpiece material. The neutral hand orientation makes it adaptable to both right-hand and left-hand toolholders. The CoroTurn 107 series is commonly used in precision turning operations where consistent chip control and dimensional repeatability are required. The insert is sold individually with a minimum order quantity of 10 units.
