Kennametal 6025897 Indexable Drill Insert Dfcds KCU40

Product Description

The KENNAMETAL 6025897 is a solid carbide indexable drill insert designed for use in indexable insert drills in metal-cutting applications. Carrying the KCU40 manufacturer grade with a TiAlN coating applied via PVD process, this insert delivers consistent cutting performance in demanding drilling operations. The insert features a 90-degree diamond shape with a DS chipbreaker, a 4.4 mm inscribed circle, and a 0.8 mm corner radius. It is sized at insert size 06T312 with a neutral hand orientation, making it suitable for standard indexable drill tooling setups. Licensed machinists and tooling specialists typically source this insert as a direct replacement component for compatible indexable drill bodies.

This insert is intended for use in industrial metal-cutting environments, including production machining, job shop drilling, and toolroom applications. The DFCDS style with DS chipbreaker geometry is well-suited for drilling steel and other ferrous materials where chip control and edge durability are priorities. The TiAlN PVD coating provides thermal resistance and wear protection, extending tool life in moderate to high cutting speed conditions. Sold individually, with a minimum order quantity of 5 units.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is secured in a vise or fixture before seating or removing inserts. Use the appropriate Torx or hex key as specified by the drill body manufacturer when torquing the insert clamp screw — do not overtighten. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper seating and runout.
