Kennametal KCGR 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. First choice for high production profiling. Unique insert clamping design offers superior rigidity. Available in chip-control geometries with both moulded and ground peripheries. Suitable for all workpiece materials.
