Kennametal 5065552 Indexable Drill Insert KCU40 6mm

Product Description

The KENNAMETAL 5065552 is a solid carbide indexable drill insert designed for use in indexable drilling operations on CNC machining centers and drill bodies that accept DFR-style inserts. This insert carries the KCU40 manufacturer grade and features a PVD-applied TiN/TiAlN dual-layer coating that provides wear resistance and thermal protection during high-speed drilling. The insert geometry is designated DFR with an LD chipbreaker, a 6 mm (0.2362 inches) inscribed circle, and a 0.40 mm (0.0156 inches) corner radius. The neutral hand orientation makes it suitable for standard drill body configurations. Tool crib technicians and machinists handling precision metalcutting applications are the primary end users.

This insert is used in industrial drilling applications where carbide grades and PVD coatings are specified for ferrous and non-ferrous materials. The LD chipbreaker geometry is suited for light to medium chip load conditions in through-hole and blind-hole drilling. The DFR insert style fits drill bodies designed for that seating geometry. Applications are typically found in production machining environments, job shops, and aerospace or automotive component manufacturing where repeatable hole quality and insert indexability are priorities.

Key Features

• KCU40 solid carbide grade with PVD-applied TiN/TiAlN dual-layer coating for thermal and abrasion resistance
• DFR insert style with LD chipbreaker for controlled chip formation during drilling
• 6 mm inscribed circle (0.2362 inches) for precise seating in compatible drill bodies
• 0.40 mm (0.0156 inches) corner radius reduces cutting-edge stress at entry and exit
• Neutral hand designation fits standard right-hand drill body configurations
• Insert size designation 020204 for accurate replacement and ordering reference

Compatibility

Designed as an OEM-style replacement indexable drill insert for drill bodies accepting DFR insert style geometry with a 6 mm inscribed circle seating. Verify drill body manufacturer specifications before installation.

Installation Notes

Indexable drill insert replacement should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before accessing the drill body insert pocket. Use the correct torque driver or hex key specified by the drill body manufacturer for the clamping screw — do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket seating surface and clamping screw for wear or damage before installing a new insert.
