Kennametal 4045195 Turning Insert CCGT32.51LF KCU10 Carbide

Product Description

The KENNAMETAL 4045195 is a solid carbide turning insert in the CCGT style, designed for precision finishing and light machining operations on CNC lathes and turning centers. It carries the ANSI insert code CCGT3251 and ISO code CCGT09T304, with an 80-degree diamond (rhombic) shape, a 1/64-inch (0.0156-inch) corner radius, and a neutral hand orientation. The KCU10 grade features a PVD-applied TiAlN coating that delivers high wear resistance across a range of workpiece materials, making it well suited for finishing passes where tight tolerances and consistent surface finish are the priority.

This insert is intended for turning, facing, and boring applications in both manual and CNC setups. Its LF chip breaker geometry is optimized for finishing and light machining cuts on steel, stainless steel, superalloys, titanium, cast iron, and aluminum. The positive rake angle and honed cutting edge style reduce cutting forces and help maintain part geometry on difficult-to-machine alloys. Typical users include CNC machinists and toolroom operators working in job shops, aerospace component manufacturing, and general precision machining environments.

Key Features

• KCU10 grade with PVD TiAlN coating for high wear resistance on steel, stainless, and superalloy workpieces
• LF chip breaker geometry optimized for finishing and light machining cuts
• 80-degree diamond insert shape with positive rake and positive side clearance for reduced cutting forces
• Honed cutting edge style for consistent performance on tight-tolerance finishing passes
• Screw-on holding method with neutral hand — compatible with standard CCGT screw-lock toolholders
• Two cutting edges per insert; multi-use across turning, facing, and boring operations

Compatibility

Designed as an OEM-style replacement turning insert for screw-on CCGT-style toolholders conforming to ANSI and ISO standards. Compatible with toolholders accepting a 3/8-inch inscribed circle CCGT insert with a screw-on holding method.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and de-energize the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key for the insert clamping screw and do not overtighten, as carbide inserts are brittle and can fracture under excessive clamp force. Confirm insert seating and toolholder cleanliness before resuming cuts.
