Hertel E211006402 Ball End Mill 1 Inch 2 Flute Hss

Product Description

The HERTEL E211006402 is a single-end ball end mill designed for milling contoured surfaces, slots, and complex 3D profiles in metalworking applications. Constructed from M7 high speed steel, this tool offers reliable toughness for general-purpose milling on a wide range of ferrous and non-ferrous materials. The uncoated finish suits applications where post-machining treatment or regrinding is expected. With a 1 inch cutting diameter, a 2.25 inch length of cut, and a 30-degree right-hand spiral helix, it delivers consistent chip evacuation and smooth finish quality. Installed and operated by machinists and toolroom professionals, it fits standard toolholders with a 1 inch shank diameter.

This ball end mill is suited for use in vertical machining centers, knee mills, and manual or CNC milling machines in job shop, production, and maintenance environments. It handles profiling, contouring, and pocket milling in medium-to-hard steels as well as softer alloys. The 2-flute configuration provides adequate chip clearance for plunge entry and slotting operations. At 4.75 inches overall length with a regular-length designation, it fits the majority of standard toolholder setups without extended-reach considerations.

Compatibility

Designed as an OEM-style replacement or standard toolroom end mill for use in any milling machine or machining center accepting a 1 inch straight shank end mill holder.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from its holder. Secure the shank fully into the collet or end mill holder to the correct engagement depth before tightening. Verify runout with a dial indicator before beginning the cut to prevent premature tool wear or workpiece damage.
