Hertel E211003601 Ball End Mill 0.5625in 2 Flute Hss

Product Description

The HERTEL E211003601 is a single-end ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in metal and similar materials. Constructed from M7 high speed steel, it features a 0.5625-inch diameter, a 2-flute spiral configuration, and a 30-degree right-hand helix that promotes efficient chip evacuation. With a 1-inch length of cut and an uncoated finish, this end mill is suited for general-purpose machining operations where consistent geometry and edge integrity are required. Machinists and tool-and-die professionals select this tool for light-to-moderate roughing and finishing passes on ferrous and non-ferrous workpieces.

This end mill is appropriate for use on manual knee mills, CNC machining centers, and similar milling equipment in job shop, maintenance, and production environments. The 0.5 inch shank diameter fits standard ER and end mill holders commonly found in both vertical and horizontal spindle setups. Its uncoated HSS construction makes it well suited for applications where regrinding is preferred over disposable coated tooling, and for use with cutting fluids to extend tool life during steel milling operations.

Key Features

• 0.5625-inch ball end diameter for contour and profile milling
• M7 high speed steel construction for durability and regrindability
• 2-flute spiral design with 30-degree helix for effective chip removal
• Right-hand cut and right-hand flute direction for standard spindle use
• Uncoated finish compatible with cutting fluid applications
• Single-end geometry with 3-inch overall length for reach versatility

Compatibility

Designed as an OEM-style replacement or direct substitute for standard 9/16-inch ball end mill applications requiring a 1/2-inch shank diameter and 2-flute HSS construction in general-purpose milling operations.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holder torque and runout specifications. Disengage spindle power and lock the table before changing tooling. Inspect the shank and holder bore for contamination or wear before seating the end mill. Always verify tool projection and secure clamping before beginning a cut.
