Kennametal 5059742 Corner Radius End Mill Head 3/4 in 5 Flute

Product Description

The KENNAMETAL 5059742 is a solid carbide corner radius end mill head from the HARVI UGDE series, designed for high-performance milling in demanding production environments. It measures 0.75 inches in diameter with a 2.25-inch length of cut and a 5-inch overall length, featuring five flutes with a 43-degree helix angle for aggressive material removal and surface finish quality. The AlTiN coating extends tool life in high-heat cutting conditions. This is a single-end, right-hand cutting and right-hand flute design with a straight shank of 0.75 inches. It is installed by CNC machinists and tooling technicians in production shops running steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

The 5059742 is suited for roughing and finishing passes on steel (ISO P), stainless steel (ISO M), and cast iron (ISO K) workpieces, as well as superalloys, titanium, and hard materials. The regular-length flute profile and helical flute geometry make it effective in general-purpose vertical and horizontal machining center applications. No chipbreaker, no coolant-through feature, and no variable helix or variable index geometry keep the design straightforward for standard milling operations. The HARVI UGDE series designation indicates this is an interchangeable head for compatible Kennametal modular tooling systems.

Compatibility

Designed for use with Kennametal HARVI UGDE series modular end mill systems. Confirm shank interface compatibility with the specific toolholder before installation. No additional model-specific compatibility data was provided with this part.

Installation Notes

Installation is performed by qualified CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing end mill heads. Torque the modular head to the toolholder per the toolholder manufacturer specification — do not estimate by feel. Verify runout with a dial indicator after seating the head to confirm proper engagement before cutting.
