Kennametal 5607206 Ball End Mill 0.5in 6 Flute Altin Carbide

Product Description

The KENNAMETAL 5607206 is a solid carbide ball end mill from the HARVI III UJBE series, designed for high-performance milling in demanding materials including steel, stainless steel, high-temperature alloys, and hardened materials. The tool features a 0.5-inch diameter, a 1.25-inch length of cut, and a 3.0-inch overall length with a straight cylindrical 0.5-inch shank. Six flutes with an unequal (variable index) flute spacing reduce chatter during both roughing and finishing operations. An AlTiN PVD coating provides thermal resistance and extends tool life in high-heat cutting environments. Cutting direction and flute direction are both right-hand.

This end mill is suited for CNC machining centers running aggressive toolpaths in ferrous and exotic alloys. The 38-degree medium helix angle promotes chip evacuation while maintaining edge stability in tough workpiece materials. The single-end configuration and centercutting geometry allow plunge entry and full-slot milling. Typical applications include die and mold work, aerospace component machining, and general precision part manufacturing where surface finish and dimensional accuracy are required in both roughing and finishing passes.

Key Features

• Variable index unequal flute spacing reduces chatter for stable cuts at higher feed rates
• AlTiN PVD coating provides oxidation resistance and thermal hardness for steel and high-temp alloy applications
• 38-degree medium helix angle supports efficient chip evacuation in deep pockets and slots
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Solid carbide construction delivers rigidity and dimensional stability at elevated cutting speeds
• Rated for roughing and finishing in a single tool across steel, stainless steel, high-temp alloys, and hardened materials

Compatibility

Designed for use in standard 1/2-inch straight shank tool holders on CNC machining centers. Primary workpiece material codes P, M, S, and H cover steel, stainless steel, high-temperature alloys, and hardened materials per ISO material classification.

Installation Notes

Installation is performed by qualified CNC machinists or tool-room technicians. Secure the straight cylindrical shank in a compatible collet or end mill holder, ensuring proper runout before operation. Verify spindle speed, feed rate, and depth of cut against the manufacturer cutting data for the specific workpiece material before initiating a cut. Do not exceed the rated length of cut of 1.25 inches to avoid deflection or tool failure.
