Kennametal 6573280 Indexable Drill Insert KCU25 Altin

Product Description

The KENNAMETAL 6573280 is a solid carbide indexable drill insert designed for precision drilling operations in metalworking and machining applications. It features an AlTiN (aluminum titanium nitride) PVD coating applied over a KCU25 carbide grade substrate, delivering improved wear resistance and heat tolerance at the cutting edge. The insert carries a 90-degree diamond shape with a 2 mm corner radius and a DS chipbreaker geometry. At 24 mm in length and sized for a 5.5 mm hole diameter, it fits standard indexable drill toolholders used in production and job-shop environments. Installation and replacement are handled by machinists and tooling technicians on CNC and manual drill setups.

This insert is suited for indexable drilling operations where consistent hole geometry and tool life are priorities. The DFC insert style and DS chipbreaker are oriented toward chip control in steel and similar ferrous materials. The neutral hand designation means it fits center or general-purpose positions within compatible indexable drill bodies. It is appropriate for use in both high-production CNC machining centers and manual toolroom applications requiring repeatable bore quality.

Key Features

• KCU25 solid carbide grade with PVD-applied AlTiN coating for extended wear resistance
• 90-degree diamond shape with 2 mm corner radius for defined cutting geometry
• DS chipbreaker designed to manage chip formation and evacuation
• Neutral hand orientation for flexible positioning within compatible drill bodies
• Insert size 9 with 5.5 mm hole diameter and 24 mm length for precise fitment

Compatibility

Designed as an OEM-style replacement indexable drill insert for use in compatible DFCDS-style indexable drill bodies requiring a size 9, 90-degree diamond insert with a 5.5 mm mounting hole.

Installation Notes

Indexable drill inserts should be installed by a qualified machinist or tooling technician. Power down and de-energize the machine spindle fully before seating or replacing any insert. Use the correct torque driver or clamping screw specified for the toolholder to secure the insert — do not over-tighten by hand. Inspect the insert pocket and clamping seat for debris or damage before installation to ensure proper seating and cutting edge alignment.
