Hertel E111103201 Ball End Mill 1/2 in 2 Flute Hss

Product Description

The HERTEL E111103201 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in a wide range of ferrous and non-ferrous materials. Built from M7 high speed steel with a bright uncoated finish, it delivers consistent performance in general-purpose machining environments. The 1/2 inch cutting diameter pairs with a 2 inch length of cut and a 37-degree right-hand spiral helix, providing smooth chip evacuation and stable cutting geometry. With a 4 inch overall length, this long-series tool extends reach for deeper cavity and pocket work without sacrificing rigidity. It is sold as a single-end tool and runs in right-hand cutting direction.

This end mill is suited for job shops, tool rooms, and production environments where long-reach ball-nose profiling is required. The long-series configuration makes it well-suited for mold and die work, deep pocket finishing, and part features that standard-length tools cannot reach. It is typically installed in CNC machining centers, knee mills, and manual milling machines using a standard collet or end mill holder sized for a 1/2 inch shank. The bright finish is appropriate for dry cutting or use with standard cutting fluids on steel, cast iron, aluminum, and similar materials.

Key Features

• 1/2 inch cutting diameter with matching 1/2 inch shank for direct collet mounting
• 2 inch length of cut for deep profiling and contour work
• 37-degree right-hand spiral helix promotes efficient chip evacuation
• M7 high speed steel construction balances toughness and wear resistance
• Long-series 4 inch overall length extends reach for deep cavities
• Bright/uncoated finish compatible with dry cutting and standard coolants

Compatibility

Designed as a general-purpose replacement or standard tooling selection for 1/2 inch shank collet holders and end mill holders used in CNC and manual milling applications.

Installation Notes

Installation is performed by machinists using a properly sized collet chuck or end mill holder torqued according to the toolholder manufacturer specifications. Confirm runout at the tool tip before cutting, as extended-reach tools amplify any spindle or holder runout. Ensure the machine spindle is fully stopped and the machine is powered down before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines when setting tool length offsets.
