Kennametal 5066197 Indexable Drill Insert Dfthp KCU40

Product Description

The KENNAMETAL 5066197 is a solid carbide indexable drill insert designed for use in indexable drilling applications on machining centers and CNC lathes. Manufactured to the DFT insert style with an HP chipbreaker, this insert features a PVD-applied TiN and TiAlN dual coating that supports wear resistance across a range of ferrous and non-ferrous workpiece materials. The inscribed circle measures 10 mm (0.3937 inches), the corner radius is 1/32 inch (0.0313 inches), and the included angle is 84 degrees, classifying it as a Trigon geometry. It is sold individually but carries a minimum order quantity of 5 units. Installation is performed by qualified machinists or toolroom technicians working with compatible indexable drill bodies.

This insert is suited for productive hole-making operations in production machining environments, including job shops, aerospace component manufacturing, and general metalworking. The HP chipbreaker geometry is intended for high-productivity drilling where chip control is critical to preventing chip packing in deep-hole applications. The insert size designation is 06T308, and the neutral hand designation means it can be applied in both right- and left-hand tooling configurations where the drill body supports it. Typical materials machined include carbon steels, alloy steels, and cast irons where a PVD-coated carbide grade such as KCU40 is appropriate.

Key Features

• 10 mm inscribed circle (0.3937 inches) with 84-degree Trigon geometry
• 1/32 inch (0.0313 inch) corner radius for controlled edge strength
• Neutral hand orientation compatible with both right- and left-hand drill bodies
• Relief angle of 9 degrees supporting positive cutting action

Compatibility

Designed as a replacement indexable drill insert for use in compatible KENNAMETAL DFT-style indexable drill bodies accepting 06T308 size inserts. Confirm drill body insert pocket specifications before ordering. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Insert replacement should be performed by a qualified machinist with the spindle locked out and the machine in a de-energized state per applicable machine safeguarding practices. Use the correct torx or hex key as specified by the drill body manufacturer to achieve proper insert seating torque. Inspect the insert pocket for wear, debris, or damage before installing a fresh insert, as a damaged pocket will affect insert stability and hole quality. Do not exceed the drill body manufacturer's recommended cutting parameters for the KCU40 grade and coating combination.
