Kennametal 5065666 Indexable Drill Insert KCU40 Carbide

Product Description

The KENNAMETAL 5065666 is a solid carbide indexable drill insert designed for use in indexable drilling operations where consistent hole quality and tool life are priorities. Carrying the KCU40 manufacturer grade and a PVD-applied TiN and TiAlN coating, this insert delivers thermal resistance and wear protection suited to production drilling environments. The insert follows the DFTHP style, incorporating an HP chipbreaker geometry that promotes efficient chip evacuation. With a 6 mm (0.2362 inch) inscribed circle, an 84-degree trigon shape, and an 8-degree relief angle, it is engineered for neutral-hand seating in compatible indexable drill bodies. Licensed metalworking technicians and CNC machinists are the primary installers.

This insert is applicable in indexable drilling applications across ferrous and non-ferrous workpieces in both job-shop and production machining environments. The DFTHP insert style is used in indexable drill systems that accept size 030304 inserts with a 0.1043 inch hole diameter for screw clamping. The HP chipbreaker geometry supports interrupted and continuous cutting conditions. This insert is sold individually with a minimum order quantity of 10 units.

Key Features

• KCU40 carbide grade with PVD-applied TiN and TiAlN dual-layer coating for thermal and abrasion resistance
• HP chipbreaker geometry promotes positive chip control and evacuation during drilling
• 84-degree trigon shape with 8-degree relief angle reduces cutting forces at the drill periphery
• 6 mm (0.2362 inch) inscribed circle and 0.40 mm (1/64 inch) corner radius for consistent sizing
• Neutral hand orientation compatible with standard indexable drill body seating
• Insert size 030304 with 0.1043 inch clamping hole for secure mechanical retention

Compatibility

Designed as an OEM-style replacement insert for indexable drill bodies that accept DFTHP-style, size 030304 trigon inserts with a 0.1043 inch hole diameter and a 6 mm inscribed circle.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key specified by the drill body manufacturer to seat the clamping screw to the tool body torque recommendation — do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert to ensure proper location and clamping force.
