Hertel E111004001 Ball End Mill 0.625 in 2 Flute Hss

Product Description

The HERTEL E111004001 is a single-end ball end mill designed for milling contoured surfaces, slots, and complex 3D profiles in metalworking applications. Built from M7 high speed steel and left uncoated, it measures 0.625 inches in diameter with a 1.625-inch length of cut and a 3.75-inch overall length. The 2-flute geometry and 37-degree right-hand spiral helix provide efficient chip evacuation while maintaining a clean finish on ferrous and non-ferrous materials. This tool is suited for manual mills and CNC machining centers where precision profile work is required.

This end mill is used in job shops, tool rooms, and production machining environments for profiling, contouring, and semi-finish milling operations. The ball-nose profile makes it well suited for die and mold work, radius pockets, and ramp-in cuts. The 0.625-inch shank diameter matches the cutter diameter for straightforward collet or end mill holder setup. It is appropriate for residential shop use and light industrial production where M7 HSS tooling is specified over carbide.

Key Features

• 0.625 inch ball-nose diameter for contour and radius milling
• M7 high speed steel construction for toughness and regrindability
• 37-degree right-hand spiral helix for efficient chip evacuation
• 1.625 inch length of cut with 3.75 inch overall length for reach into moderate-depth features
• Uncoated finish suitable for use with cutting fluids on a wide range of materials
• Single-end design with right-hand cutting direction

Compatibility

Designed as a standard 0.625-inch shank ball end mill compatible with collet chucks, end mill holders, and milling machine spindles accepting 5/8-inch straight-shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the tool. Seat the shank fully in the holder and torque retention screws or collet nuts per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates wear on HSS tooling.
