Kennametal 6025828 Indexable Drill Insert Dftds KCU40

Product Description

The KENNAMETAL 6025828 is a solid carbide indexable drill insert in the DFTDS style, designed for use in compatible indexable drill bodies. Carrying the KCU40 manufacturer grade with a PVD-applied TiAlN coating, this insert is built for demanding hole-making operations where tool life and chip control are critical. The trigon (84-degree included angle) geometry with a DS chipbreaker promotes controlled chip evacuation in a range of workpiece materials. With a 4.4 mm inscribed circle and a 0.8 mm corner radius, it is sized for drilling at a 0.173-inch hole diameter. Installation is performed by qualified machinists and toolroom technicians.

This insert is suited for use in CNC machining centers, drill presses, and turning centers equipped with compatible KENNAMETAL indexable drill bodies. The neutral hand configuration allows for straightforward fitment in standard drill body pockets. Applications include production drilling in steel, stainless steel, and other materials where a TiAlN-coated carbide insert provides adequate wear resistance and thermal stability. The DFT insert style and DS chipbreaker combination targets efficient chip control in through-hole and blind-hole drilling operations.

Key Features

• KCU40 grade solid carbide substrate with PVD TiAlN coating for wear and heat resistance
• DS chipbreaker geometry promotes reliable chip control during drilling
• 84-degree included angle trigon shape for stable cutting action
• 4.4 mm inscribed circle sized for 0.173-inch hole diameter applications
• 0.8 mm corner radius reduces edge stress and supports surface finish
• Neutral hand insert fits standard DFT-style indexable drill body pockets

Compatibility

Designed as an OEM-style replacement or direct-fit insert for indexable drill bodies accepting DFT-style inserts with an 06T308 insert size designation. Verify pocket geometry and insert size against the drill body specification before ordering.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Shut down and lock out the machine spindle before seating or indexing any insert. Use the correct torx or hex key to the insert screw as specified by the drill body manufacturer — do not overtighten. Inspect the pocket seat and clamping screw for wear or damage before installing a new insert.
