Kennametal 6025827 Indexable Drill Insert KCU40 Carbide

Product Description

The KENNAMETAL 6025827 is a carbide indexable drill insert designed for use in indexable drill tooling systems. Manufactured to insert size 06T308 with an 84-degree included angle and a Trigon shape, this insert features a TiAlN coating applied via a PVD process. The KCU40 grade carbide substrate is suited for demanding drilling applications where tool life and edge stability are priorities. A 0.80 mm corner radius and DS chipbreaker geometry work together to manage chip formation and reduce cutting forces. Licensed machinists and CNC operators in metalworking shops are the primary installers and users of this insert.

This insert is intended for use in compatible KENNAMETAL indexable drill bodies that accept the DFTDS insert style. Typical applications include drilling operations on ferrous and non-ferrous metals in production machining environments, both horizontal and vertical machining centers. The neutral hand designation makes it suitable for standard right-hand drill body configurations. The DS chipbreaker is engineered for controlled chip evacuation in through-hole and blind-hole drilling scenarios common in aerospace, automotive, and general metalworking applications.

Key Features

• KCU40 carbide grade with PVD-applied TiAlN coating for extended tool life in demanding drilling operations
• 84-degree included angle Trigon shape (insert size 06T308) for indexable drill compatibility
• DS chipbreaker geometry promotes controlled chip formation and evacuation
• 0.80 mm corner radius balances edge strength and surface finish at the drill exit
• Neutral hand orientation fits standard right-hand indexable drill body configurations
• Inscribed circle of 4.40 mm with a 0.1730 inch hole diameter for secure clamping in the drill body pocket

Compatibility

Designed for use in KENNAMETAL indexable drill bodies that accept the DFTDS insert style. Verify drill body insert pocket specifications against insert size 06T308 before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be powered down and the tool assembly secured before indexing or replacing inserts. Use the correct torque driver or wrench 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 for chips or debris before seating the new insert to ensure full and even contact.
