Kennametal KC850 – Grooving/Parting Carbide Insert

The Kennametal KC850 grooving/parting carbide insert excels in heavy cutting applications on general materials, where its tin coating provides a reliable balance of wear resistance and chip formation. With a 3.18 mm cutting width and 6.35 mm maximum depth, this insert is well-suited for removing significant material from workpieces, making it a valuable asset for CNC operators who require efficient and consistent results. Its left-hand orientation and Top Notch series design make it a versatile choice for a range of grooving and parting operations.
