Kennametal 5059453 Corner Radius End Mill Head 1/4 in

Product Description

The KENNAMETAL 5059453 is a solid carbide corner radius end mill head from the HARVI UGDE series, designed for high-performance milling in demanding machining environments. With a 1/4 inch diameter, a 3/4 inch length of cut, and 5 helical flutes, this single-end tool is engineered for efficient chip evacuation and surface finish quality. The AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures, extending tool life in abrasive and hard-material applications. The 43-degree helix angle promotes smooth cutting action and reduces radial cutting forces during the milling operation.

This end mill head is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials in both roughing and finishing passes. The right-hand flute direction and right-hand cutting orientation make it compatible with standard CNC machining center spindles. The straight shank measures 1/4 inch in diameter, matching the mill diameter for direct toolholder engagement. This tool is typically installed and applied by machinists and CNC programmers working in job shop, aerospace, die and mold, and general metalworking environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard-material cutting
• AlTiN coating extends tool life in high-temperature and abrasive machining conditions
• 5-flute helical design improves chip evacuation and surface finish
• 43-degree helix angle reduces cutting forces and chatter during milling
• Single-end configuration with right-hand cut and right-hand flute direction
• No chipbreaker, no coolant-through design — suited for external coolant delivery setups

Compatibility

Part of the KENNAMETAL HARVI UGDE series. Designed for use with compatible modular tooling systems that accept a 1/4 inch straight shank end mill head. Verify toolholder interface compatibility with the UGDE system before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before inserting or removing the tool head. Ensure the toolholder bore and clamping mechanism are clean and free of debris before seating the shank. Confirm runout with a dial indicator after clamping to avoid premature edge wear or dimensional inaccuracy.
