Kennametal 5065559 Indexable Drill Insert KCU40 Carbide

Product Description

The KENNAMETAL 5065559 is a solid carbide indexable drill insert designed for use in indexable insert drills in metal-cutting operations. It features a parallelogram (DFR) insert style with an MD chipbreaker geometry and is manufactured from carbide in the KCU40 grade, finished with a PVD-applied TiAlN coating for improved wear resistance and heat tolerance at the cutting edge. The inscribed circle measures 2.5 mm, the corner radius is 1/64 inch, and the insert carries a neutral hand orientation. This insert is intended for professional machinists and toolroom technicians working in production drilling applications on ferrous and non-ferrous materials.

This insert is suited for light-to-moderate drilling operations where a small-diameter, precision insert is required. The MD chipbreaker geometry is optimized for chip control in drilling applications. The DFR insert style fits indexable drill bodies that accept this specific pocket configuration. Typical install environments include CNC machining centers, turning centers with live tooling, and manual drill press setups where indexable tooling systems are used. Insert size designation is 30204.

Key Features

• KCU40 carbide grade with PVD TiAlN coating for thermal and wear resistance
• MD chipbreaker geometry for effective chip evacuation during drilling
• 2.5 mm inscribed circle for small-diameter precision insert applications
• 1/64 inch corner radius for controlled cutting edge geometry
• Neutral hand orientation for flexible toolholder compatibility
• Parallelogram (DFR) insert style for secure seating in compatible drill bodies

Compatibility

Designed as a replacement-style indexable drill insert for KENNAMETAL indexable drill bodies that accept DFR-style, parallelogram-shaped inserts with a 2.5 mm inscribed circle pocket configuration.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and spindle locked. Use the correct torx or hex key specified by the drill body manufacturer to seat the insert — do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket for debris or damage before seating a new insert. Handle solid carbide inserts carefully to avoid chipping the cutting edge prior to use.
