Kennametal 5065664 Indexable Drill Insert Dftmd KCU40

Product Description

The KENNAMETAL 5065664 is a carbide indexable drill insert in the DFTMD style, designed for use in modular indexable drilling systems. It features a Trigon (84-degree included angle) geometry and is manufactured to KCU40 grade carbide with a PVD-applied TiN/TiAlN multilayer coating. The insert carries a neutral hand designation and an inscribed circle diameter of 0.2362 inches (6.00 mm), with a corner radius of 0.0156 inches (0.40 mm) and an 8-degree relief angle. This insert is sized at ISO insert size 030204. It is installed and replaced by machinists and CNC tooling technicians in production drilling operations.

This insert is suited for indexable drill bodies that accept DFTMD-style inserts in the DFT series format. It is used in moderate-to-high-demand metal cutting applications where a multilayer PVD coating provides thermal resistance and extended edge life. The insert size and geometry make it a fit for smaller-diameter modular drill heads targeting bore diameters in the range supported by a 6.00 mm inscribed circle. Applicable in both horizontal and vertical machining center configurations.

Key Features

• KCU40 carbide grade with PVD-applied TiN/TiAlN multilayer coating for wear and thermal resistance
• Trigon shape with 84-degree included angle and 8-degree relief angle for aggressive chip clearance
• Inscribed circle of 0.2362 inches (6.00 mm) and ISO size 030204
• Corner radius of 0.0156 inches (0.40 mm) for controlled edge geometry
• Neutral hand orientation for flexible mounting
• MD chipbreaker geometry for reliable chip formation in drilling operations

Compatibility

Designed as an OEM-style replacement insert for KENNAMETAL DFT-series indexable drill bodies that accept DFTMD insert style at the 030204 size designation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to the drill body manufacturer's specified seating procedure — do not overtighten the clamping screw. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact.
