Kennametal SPMR Inserts

Turning insert with a CVD tri-phase coating on an extra-strong, cobalt-enriched alloyed substrate. Designed for heavy cutting of low medium and high-carbon steel, medium hardness alloy and tool steel, stainless steel and some high temperature alloys. Excellent thermal and mechanical shock resistance makes grade KC850 ideally suited for difficult drilling applications. Used in inserts for Kendex/Metcut drill bodies. Kendex positive inserts are your the first choice for productive machining of high temperature alloys on medium to large lathes. Available in flat top geometries with ground periphery.
