Kennametal 6025898 Indexable Drill Insert Dfcds KCU40

Product Description

The KENNAMETAL 6025898 is a solid carbide indexable drill insert designed for use in indexable drilling tool bodies requiring a DFCDS-style insert. Manufactured from carbide with a TiAlN coating applied via PVD process, this insert is engineered to deliver reliable cutting performance and extended tool life in demanding drilling operations. It features a 90-degree diamond shape with a 4.4 mm inscribed circle and a 0.8 mm corner radius. The DS chipbreaker geometry promotes efficient chip evacuation during drilling. This insert is suitable for CNC machining centers and is installed by machinists, tooling technicians, and metalworking professionals in production environments.

This insert is intended for use in indexable drill systems that accept DFCDS-style, diamond-shaped inserts with a 4.4 mm inscribed circle. Typical applications include hole-making operations in ferrous and non-ferrous materials on CNC machining centers and drill presses where indexable tooling is preferred over solid-drill solutions. The neutral hand designation makes it compatible with center or outer cutting positions depending on the drill body specification. Confirm insert position requirements with the drill body documentation before installation.

Key Features

• Solid carbide construction with PVD-applied TiAlN coating for heat and wear resistance
• DFCDS insert style with DS chipbreaker for controlled chip formation
• 90-degree diamond shape with 4.4 mm inscribed circle
• 0.8 mm corner radius for edge strength and surface finish support
• Neutral hand designation for flexible positioning in compatible drill bodies
• KCU40 manufacturer grade optimized for indexable drilling applications

Compatibility

Designed as a direct OEM-grade replacement insert for indexable drill bodies accepting DFCDS-style diamond inserts with a 4.4 mm inscribed circle and 90-degree included angle.

Installation Notes

Installation of indexable cutting inserts should be performed by qualified machinists or tooling technicians. De-energize and lock out the machine before accessing the tool body. Use the correct torx or hex key specified by the drill body manufacturer to seat the insert; do not overtighten. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert.
