Kennametal 4050696 CNMG433UP KCU10 Turning Insert

Product Description

The KENNAMETAL 4050696 is a CNMG433UP indexable turning insert in the KCU10 grade, designed for steel, stainless steel, and superalloy machining. It features a solid carbide substrate with a PVD-applied TiAlN coating that delivers high wear resistance across a wide range of cutting conditions. The insert geometry uses a negative rake angle with a honed cutting edge and a UP chip breaker optimized for roughing and medium machining operations. With a 0.5-inch inscribed circle and a 3/64-inch corner radius, this insert handles moderate-to-aggressive depths of cut in turning, facing, and boring applications. Four available cutting edges extend tool life per insert.

This insert is suited for CNC turning centers running steel, stainless steel, cast iron, superalloys, titanium, aluminum, and hardened materials. The KENLOC series insert is designed for use in CNMG-style toolholders with clamp or pin holding methods. Typical applications include continuous and interrupted roughing passes and medium finishing cuts in both horizontal and vertical lathe setups in production and job shop environments. Licensed machinists and CNC operators handling ferrous and exotic-alloy components are the primary installers.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified procedure when seating the clamp or pin. Inspect the toolholder pocket and seating surfaces for chips or damage before installing a new insert to ensure proper seating and safe cutting forces.
