Hertel E211010801 Ball End Mill 1.125in 2 Flute Hss

Product Description

The HERTEL E211010801 is a single-end ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in metal workpieces. Manufactured from M7 high speed steel, it features a 1.125-inch diameter with a 2.25-inch length of cut and an overall length of 4.75 inches. The two-flute spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The uncoated finish makes it well suited for general-purpose milling applications where regrinding and reconditioning are part of the tool management workflow. A licensed machinist or toolroom operator typically selects this end mill for profiling and finish passes on ferrous and non-ferrous materials.

This end mill is used in manual milling machines and CNC machining centers for applications requiring a ball-nose profile, including die and mold work, cavity milling, and contour finishing. The 1.0-inch shank diameter allows it to seat securely in standard end mill holders and collet chucks sized for that shank. The right-hand cutting and right-hand flute direction are consistent with standard spindle rotation on conventional vertical milling setups. It is a single-end tool with no extended reach geometry, making it appropriate for standard-depth profiling work where rigidity is a priority.

Key Features

• 1.125-inch ball nose diameter for contoured surface and profile milling
• M7 high speed steel construction for toughness and resharpening capability
• 2-flute spiral design with 30-degree helix angle for efficient chip evacuation
• 2.25-inch length of cut suitable for moderate-depth profiling passes
• 1.0-inch shank diameter compatible with standard end mill holders
• Uncoated finish — ready for regrinding or use with cutting fluids

Compatibility

Designed as a standard single-end ball end mill with a 1.0-inch straight shank, compatible with end mill holders, collet chucks, and milling arbors sized for a 1.0-inch shank diameter on vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is secured in the holder to the correct insertion depth before tightening set screws or collet nuts to the holder manufacturer specifications. Verify runout after installation to minimize premature wear. Follow applicable shop safety protocols and machine guarding requirements during setup and operation.
