Kennametal 4045144 VNGG432LF KCU10 Turning Insert

Product Description

The KENNAMETAL 4045144 is a solid carbide turning insert in the VNGG432LF geometry with KCU10 grade, coated with TiAlN via PVD process. It carries a 35-degree diamond (rhombic) shape with a 0.5-inch inscribed circle and a 1/32-inch corner radius. Designed for finishing and light machining operations, it delivers high wear resistance across a range of primary workpiece materials including steel, stainless steel, cast iron, and superalloys. With 4 cutting edges and a neutral hand, this insert suits high-production turning, facing, boring, back turning, and back boring setups on CNC lathes and turning centers.

This insert fits applications in the KENLOC series toolholding system and is suited for residential machine shops, production facilities, and contract manufacturers running steel and stainless components. The LF chip breaker geometry is optimized for finishing and light cuts, reducing vibration and improving surface finish on tight-tolerance parts. It is appropriate for ISO material groups P, M, K, N, S, and H, making it a versatile option when tool changes between material types are required. Machinists and CNC operators working with superalloys and titanium will benefit from the KCU10 grade characteristics at this insert geometry.

Key Features

• TiAlN PVD coating provides high wear resistance for steel, stainless steel, and cast iron applications
• 35-degree diamond (V) insert shape with 1/32-inch corner radius for fine-detail finishing passes
• LF chip breaker designed for finishing and light machining with reduced cutting forces
• 4 cutting edges maximize tooling value per insert
• Neutral hand insert compatible with standard VNGG-style clamp and pin toolholders
• Meets ANSI and ISO standards; ANSI code VNGG432, ISO code VNGG220408

Compatibility

Designed for use in KENLOC series toolholders accepting VNGG432 inserts with clamp and pin retention. Compatible with toolholding systems that conform to ANSI insert code VNGG432 and ISO insert code VNGG220408.

Installation Notes

Installation is performed by CNC machinists or tool-room technicians. Power down and lock out the machine spindle before seating or indexing any insert. Use the appropriate torx or hex key to secure the clamp and pin to the toolholder manufacturer torque specification. Inspect the insert pocket and clamp for wear or debris before seating a new cutting edge to ensure proper seating and repeatable tool geometry.
