Kennametal 5066147 Indexable Drill Insert Dftmd KCU40 Trigon

Product Description

The KENNAMETAL 5066147 is a solid carbide indexable drill insert designed for use in indexable drill tooling systems. It carries the KCU40 manufacturer grade and features a PVD-applied dual coating of TiN and TiAlN for improved wear resistance and heat management at the cutting edge. The insert is configured in the Trigon (84-degree included angle) shape with a DFT style designation and MD chipbreaker geometry. Key dimensional specs include a 12 mm (0.4724 inch) inscribed circle, a thickness of 0.1875 inches, and a corner radius of 0.79 mm (0.0313 inches). This insert is installed and replaced by machinists and CNC tooling technicians in production drilling applications.

This insert is suited for indexable drill bodies that accept DFT-style Trigon inserts with an 84-degree included angle and a 12 mm inscribed circle. The MD chipbreaker geometry is intended for moderate cutting conditions across a range of workpiece materials. With a neutral hand orientation, the insert fits standard right-hand drill bodies without a handed insert requirement. Typical applications include through-hole and blind-hole drilling in metal components across job shop and production machining environments.

Installation Notes

This insert is installed and indexed by machinists or CNC tooling technicians. Shut down and lock out the machine spindle before replacing or indexing any insert. Use the correct torx or insert-clamping wrench specified by the drill body manufacturer to achieve proper seating torque — do not overtighten by hand estimation. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.
