March 2012 sees the introduction of a new range of turning inserts from Sandvik Coromant. Spectrum turning is a minimum program that provides a simplified choice of inserts designed to efficiently machine different materials at various cutting conditions.

Excellent for different small batch production, Spectrum turning grades and geometries take away the complication of having several different tools for different jobs.

Whether external or internal machining, rough turning or finishing, machining continuously or with interrupted cuts, these inserts have been designed to be as versatile as possible, delivering high performance output in terms of reliability, tool life and chip control.

The grades can be used for turning in steels, stainless steels, HRSA, cast irons, titanium and nonferrous materials. Two grades are being launched: GC15 combines high strength micro-grain cemented carbide with a thin, PVD coating that adds edge strength and wear resistance. GC30 has high bulk toughness with a gradient cemented carbide substrate and a highly wear- and heat-resistant CVD coating.
