Kennametal 6025665 Indexable Drill Insert KCU40 Trigon

Product Description

The KENNAMETAL 6025665 is a solid carbide indexable drill insert designed for use in indexable drilling toolholders. It carries the KCU40 manufacturer grade and features a Physical Vapor Deposition (PVD)-applied TiAlN coating for extended tool life in demanding cutting applications. The insert is Trigon-shaped with an 84-degree included angle, a 4.4 mm inscribed circle, a thickness of 0.125 inches, and a 0.8 mm corner radius. The DS chipbreaker geometry aids in chip control during drilling operations. This insert is installed and serviced by machinists and toolroom technicians working with indexable drilling systems.

This insert is suited for precision drilling operations in metalworking environments, including production machining, job shop drilling, and automated CNC drilling cells. The TiAlN coating provides heat resistance and wear protection, making it appropriate for dry or minimal-lubrication cutting strategies in ferrous and non-ferrous materials. The neutral hand orientation allows flexible positioning within compatible toolholders. Insert size designation is 070408.

Installation Notes

This insert is installed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before replacing any indexable insert. Use the correct insert clamping torque as specified by the toolholder manufacturer documentation — do not rely on hand-feel alone. Inspect the insert pocket and clamping screw for wear or damage before seating the new insert.
