Hertel E211005601 Ball End Mill 0.875 in 2 Flute Hss

Product Description

The HERTEL E211005601 is a single-end ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in a wide range of workpiece materials. Built from M7 high speed steel, this tool measures 0.875 inches in diameter with a 2-inch length of cut and a 4.25-inch overall length. The 7/8-inch shank diameter matches the mill diameter for straightforward toolholder setup. The uncoated finish makes it suitable for general-purpose milling applications where coating is not required. Installed by machinists and tool-and-die professionals, this end mill is a standard choice for shops running manual or CNC milling equipment on ferrous and non-ferrous workpieces.

This ball end mill is suited for use on vertical and horizontal milling machines as well as CNC machining centers in both job shop and production environments. The 2-inch length of cut allows access to moderate-depth features such as pockets, ramps, and sculpted profiles. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during profiling passes. With two flutes and a right-hand spiral, right-hand cutting direction, this tool performs well in lighter-feed applications and on materials where chip clearance is a priority.

Key Features

• 0.875-inch (7/8-inch) ball end diameter for contour and profile milling
• M7 high speed steel construction for general-purpose durability
• 2-inch length of cut for moderate-depth pocket and profile work
• 30-degree helix angle promotes efficient chip evacuation
• Right-hand cut, right-hand spiral flute geometry
• Uncoated finish — no coating compatibility concerns for re-sharpening

Compatibility

Designed as an OEM-style single-end ball end mill compatible with standard 7/8-inch bore milling toolholders and collet chucks used on vertical mills and CNC machining centers.

Installation Notes

This end mill is installed by machinists in standard 7/8-inch end mill holders, collet chucks, or shrink-fit toolholders. Ensure the machine spindle is fully stopped and the toolholder is clean and free of chips before installing or removing the tool. Verify runout at the toolholder before beginning cutting operations to avoid premature tool wear. Follow the machine manufacturer's recommended speeds and feeds for the workpiece material and tool diameter.
