Kennametal 5066190 Indexable Drill Insert Dftmd KCU40

Product Description

The KENNAMETAL 5066190 is a solid carbide indexable drill insert designed for use in indexable drilling tool bodies that accept DFT-style inserts. Manufactured to grade KCU40 with a PVD-applied TiN and TiAlN dual coating, this trigon-shaped insert delivers wear resistance and thermal stability in demanding drilling applications. It features an 84-degree included angle, a 0.5906-inch (15 mm) inscribed circle, a thickness of 0.2067 inches, and a corner radius of 0.0313 inches (0.79 mm). The MD chipbreaker geometry supports efficient chip evacuation in a range of workpiece materials. Installation is performed by qualified machinists and tooling technicians.

This insert is suited for indexable drilling operations in metalworking environments, including production machining, job shop drilling, and automated CNC applications. The neutral hand designation makes it adaptable across multiple drilling setups. The PVD TiN and TiAlN coating extends tool life in ferrous and non-ferrous materials where heat buildup and abrasive wear are primary concerns. The DFT insert style and size designation 090508 define the compatible toolholder interface.

Key Features

• Grade KCU40 solid carbide substrate with PVD TiN and TiAlN dual coating for wear and heat resistance

• 0.5906-inch (15 mm) inscribed circle with 0.0313-inch corner radius
• Neutral hand orientation compatible with standard DFT-style indexable drill bodies
• 8-degree relief angle supports clean cutting action in indexable drilling applications
• Mounting hole diameter of 0.2165 inches for secure clamping in the toolholder pocket

Compatibility

Designed as an OEM-style replacement insert for indexable drill toolholders accepting DFT insert style, size 090508, with a 15 mm inscribed circle and trigon geometry.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician following the toolholder manufacturer's torque and seating procedures. Power down and lock out the machine before indexing or replacing inserts. Inspect the toolholder pocket and clamping screw for wear or damage before installing a new insert. Do not exceed the recommended cutting parameters for grade KCU40 as specified in the toolholder manufacturer's documentation.
