Hertel E211000804 Ball End Mill 0.125 in 2 Flute Hss

Product Description

The HERTEL E211000804 is a single-end ball end mill designed for contour milling, slotting, and profiling operations in metal and alloy workpieces. Built from M7 high speed steel with a bright uncoated finish, this tool offers solid performance in general-purpose machining applications. It features a 0.125 inch cutting diameter, a 0.375 inch length of cut, and a 30-degree right-hand spiral helix with 2 flutes. The shank diameter is 0.375 inches and the overall length measures 2.3125 inches. This end mill is installed by machinists and toolroom professionals running manual or CNC milling equipment.

This end mill suits light to medium-duty milling work on steel, cast iron, aluminum, and similar materials in job shop, toolroom, and production environments. The ball nose geometry is well suited for 3D contouring, radius profiling, and finishing passes where a full-radius tip is required. Its regular-length configuration fits standard tool holders and collet chucks across common vertical and horizontal milling setups.

Key Features

Compatibility

Designed as a standard single-end ball end mill compatible with any milling machine tool holder or collet chuck accepting a 0.375 inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the milling machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware per the tool holder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut to avoid premature tool wear or workpiece damage.
