Hertel E211202601 Ball End Mill 0.4063 in 2 Flute Hss

Product Description

The HERTEL E211202601 is a double-end ball end mill designed for milling operations requiring a full-radius cutting profile. Manufactured from M7 grade high speed steel, this tool delivers reliable performance in general-purpose milling applications including contour milling, slotting, and profiling. The double-end design provides two usable cutting ends, extending tool life between changes. With a 0.4063-inch cutting diameter and a 30-degree right-hand spiral helix, it produces a smooth cutting action across a range of workpiece materials. The uncoated finish makes it straightforward to inspect for wear. It is suited for use in manual mills and CNC machining centers.

This ball end mill is intended for use in machine shops, tool rooms, and production environments where a 13/32-inch ball nose profile is required. The 0.8125-inch length of cut accommodates moderate-depth passes, and the 1/2-inch shank diameter fits standard collets and end mill holders. Both right-hand cutting and right-hand flute direction support conventional and climb milling setups. It is a regular-length tool appropriate for close-tolerance work where reach is not a limiting factor.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Verify the tool is secured to the correct engagement depth in the collet or holder before operation. Consult the machine tool manufacturer guidelines and applicable shop safety standards for appropriate speeds and feeds based on workpiece material.
