Kennametal 4053364 Turning Insert DNGG432LF KCU10 Carbide

Product Description

The KENNAMETAL 4053364 is a solid carbide turning insert with ANSI designation DNGG432LF and ISO designation DNGG150408LF, finished with a PVD-applied TiAlN coating and assigned grade KCU10. The 55-degree diamond (rhombic) insert shape provides a sharp, precise cutting profile suited for finishing and light machining operations. With a 0.5-inch inscribed circle, a 0.1875-inch insert thickness, and a 0.0313-inch corner radius, this insert fits standard KENLOC-series toolholders using clamp or pin holding. It is designed for licensed machinists and CNC lathe operators working in high-production or precision turning environments.

This insert is applied in turning, facing, boring, back turning, and back boring operations. Its LF chip breaker geometry and honed cutting edge make it particularly effective for finishing cuts on steel, stainless steel, cast iron, superalloys, and titanium (workpiece material codes P, M, K, N, S, H). The KCU10 grade delivers high wear resistance with moderate toughness across these material groups, making it a reliable choice for consistent surface finish results in both manual and CNC turning setups.

Key Features

• 55-degree diamond (rhombic) insert shape with negative rake and negative side clearance for stable chipload
• TiAlN PVD coating on solid carbide substrate provides thermal resistance and extended tool life on ferrous and exotic materials
• LF chip breaker geometry optimized for finishing and light machining operations
• Four usable cutting edges per insert for reduced tooling cost per edge
• Maximum depth of cut of 0.4065 inches (13/32 inches) supports a wide range of finishing passes
• Conforms to ANSI and ISO insert standards for broad toolholder compatibility

Compatibility

Designed for use with KENLOC-series toolholders accepting DNGG-style inserts with clamp or pin holding. Compatible with ANSI insert code DNGG432 and ISO insert code DNGG150408. Suitable for multi-use applications including turning, facing, boring, back turning, and back boring on steel, stainless steel, cast iron, aluminum, superalloys, and titanium workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and all energy isolated before seating or replacing inserts. Use the correct clamp or pin holding hardware specified for KENLOC-series toolholders and ensure the insert pocket is clean and free of chips before seating. Inspect the cutting edge and chip breaker for damage before each use; do not reuse a chipped or fractured insert.
