Kennametal 5065557 Indexable Drill Insert Dfrld KCU40

Product Description

The KENNAMETAL 5065557 is a solid carbide indexable drill insert designed for use in indexable drill tooling systems. It carries the KCU40 manufacturer grade and features a PVD-applied TiN/TiAlN multilayer coating that improves wear resistance and extends tool life in demanding drilling operations. The insert follows the DFRLD style with an LD chipbreaker geometry and a neutral hand orientation. Key dimensions include a 6 mm (0.2362 inch) inscribed circle, a thickness of 0.1126 inches, and a corner radius of 1/64 inch (0.0156 inches). Installation and replacement are handled by machinists, toolroom technicians, and CNC operators working with compatible indexable drill bodies.

This insert is suited for precision drilling applications in metalworking environments, including production machining, job shops, and toolroom operations. The TiN/TiAlN PVD coating performs well across a range of ferrous and non-ferrous workpiece materials where controlled chip evacuation and edge stability are required. The LD chipbreaker promotes efficient chip formation during through-hole and blind-hole drilling cycles. This insert ships individually and is sold with a minimum order quantity of 5 units.

Key Features

• Solid carbide construction with KCU40 manufacturer grade for high-strength cutting performance
• PVD-applied TiN/TiAlN multilayer coating for improved wear resistance and thermal stability
• LD chipbreaker geometry for controlled chip formation in drilling operations
• Neutral hand insert orientation compatible with standard DFRLD-style drill bodies
• 6 mm inscribed circle with a 0.40 mm (1/64 inch) corner radius for precise edge geometry
• Insert size designation 030204 for accurate cross-referencing and toolholder matching

Compatibility

Designed as a replacement insert for DFRLD-style indexable drill bodies requiring a 6 mm inscribed circle insert with an LD chipbreaker and KCU40 carbide grade. Confirm toolholder seat geometry and insert size code 030204 before installation.

Installation Notes

Insert replacement should be performed by qualified machinists or toolroom personnel with the machine powered down and locked out before any tooling change. Use the appropriate torx or hex key as specified by the drill body manufacturer when seating and torquing the clamping screw — do not overtighten. Inspect the insert pocket and clamping components for wear or debris before installing a new insert. Follow the toolholder manufacturer's setup instructions and applicable shop safety procedures.
