Kennametal 5065554 Indexable Drill Insert KCU40 6mm

Product Description

The KENNAMETAL 5065554 is a solid carbide indexable drill insert designed for use in indexable drill bodies requiring DFR-style inserts with a GD chipbreaker geometry. Coated with TiN and TiAlN via a PVD process, this insert delivers wear resistance and thermal stability in drilling applications across a range of workpiece materials. It features a 6 mm (0.2362 inches) inscribed circle, a thickness of 0.1098 inches, and a corner radius of 0.0156 inches (1/64 inch, 0.40 mm). The KCU40 grade is suited for demanding cutting conditions. Installation and replacement are performed by machinists and tooling technicians on CNC and manual drilling equipment.

This insert is applied in metal cutting and machining operations where indexable drilling tooling is used. Typical applications include hole-making in ferrous and non-ferrous materials in production machining environments, job shops, and manufacturing facilities. The neutral hand orientation makes it suitable for use on both left- and right-hand spindle configurations depending on the drill body design. The GD chipbreaker geometry aids in chip control during through-hole and blind-hole drilling operations.

Key Features

• DFR insert style with GD chipbreaker geometry for controlled chip evacuation
• KCU40 grade solid carbide construction for strength and wear resistance
• TiN and TiAlN dual-layer PVD coating for thermal and abrasion resistance
• 6 mm inscribed circle (0.2362 inches) with 0.40 mm corner radius
• Neutral hand orientation for broad compatibility with indexable drill bodies
• Insert size designation 020204 for precise tooling system matching

Compatibility

Designed as an OEM-style replacement indexable drill insert for KENNAMETAL indexable drill bodies requiring DFR-style inserts in the KCU40 grade with a GD chipbreaker. Verify insert size designation 020204 and hole diameter of 0.0906 inches against the target drill body specification before ordering.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate Torx or socket-head key as specified by the drill body manufacturer to secure the insert clamp screw to the correct seating torque per the toolholder documentation. Inspect the insert pocket for wear or debris before installing a new insert to ensure proper seating and runout control.
