Hertel E211204001 Ball End Mill 0.625in 2 Flute Hss

Product Description

The HERTEL E211204001 is a double-end ball end mill designed for milling contoured surfaces, slots, and complex 3D profiles on a wide range of workpiece materials. Constructed from M7 high speed steel in an uncoated finish, it measures 0.625 inches in diameter with a 1.125-inch length of cut and a 4.5-inch overall length. The two-flute spiral configuration with a 30-degree right-hand helix provides efficient chip evacuation and smooth cutting action. This tool is intended for use by machinists and toolroom professionals operating manual mills, knee mills, and CNC machining centers.

This ball end mill is suited for light to medium material removal in steels, aluminum, plastics, and similar machinable materials where a ball-nose profile is required. The double-end design extends tool life by providing two usable cutting ends, making it a practical choice for job shop and production environments. Its regular length classification means it fits standard tool holders without requiring extended-reach adapters. The 0.625-inch shank diameter matches the cutting diameter for direct chuck or collet mounting.

Key Features

• Double-end design provides two cutting ends, extending usable tool life
• M7 high speed steel construction offers toughness in interrupted and general-purpose cuts
• 30-degree right-hand helix promotes chip flow and reduces cutting forces
• Two-flute spiral geometry suits slotting and profiling in a variety of materials
• Uncoated finish maintains sharp edge geometry without coating buildup concerns
• Regular length classification fits standard collet chucks and end mill holders

Compatibility

Designed as a standard 0.625-inch shank ball end mill compatible with collet chucks, end mill holders, and milling machine spindles accepting 0.625-inch round shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following all machine-specific lockout and spindle stop procedures before tool changes. Secure the shank fully within the collet or end mill holder to the recommended engagement depth per the toolholder manufacturer guidelines. Verify runout with a dial indicator after mounting to ensure concentricity before cutting. Consult speeds and feeds tables for M7 high speed steel tooling appropriate to the workpiece material before beginning any cut.
