Hertel E2050015 Square End Mill 15/64 in 2 Flute Cobalt

Product Description

The HERTEL E2050015 is a double-end cobalt square end mill designed for metal-cutting operations in milling machines and machining centers. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to harder ferrous and non-ferrous materials. The 15/64-inch (0.2344 inches) cutting diameter pairs with a 1/2-inch length of cut and a 30-degree right-hand spiral helix for efficient chip evacuation. With two flutes and a centercutting geometry, this end mill handles both slotting and plunge operations. Machinists and tool-and-die professionals select this style for general-purpose milling where a cobalt grade outperforms standard HSS.

This end mill fits standard toolholding setups that accept a 3/8-inch shank diameter. The double-end design provides two usable cutting ends, extending service life before the tool is retired. The bright, uncoated finish makes it a practical choice for applications where coating cost is not justified or where re-sharpening is planned. It is appropriate for job shops, maintenance machining, and production environments working with mild steel, alloy steel, cast iron, aluminum, and similar materials at conventional cutting speeds.

Key Features

• M42 cobalt HSS construction for improved heat resistance over standard HSS grades
• Double-end design provides two cutting ends per tool
• Centercutting geometry supports direct plunge entry
• 30-degree right-hand helix promotes smooth chip flow in spiral flutes
• Bright/uncoated finish suitable for re-sharpening or cost-sensitive applications
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed for use in milling machines and machining centers with toolholders accepting a 3/8-inch shank diameter. Suitable as a general-purpose square end mill for conventional milling applications.

Installation Notes

Installation and operation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the toolholder. Verify toolholder runout and set correct cutting parameters for the workpiece material before engaging the cut. Do not exceed the recommended depth of cut for the flute length or shank diameter.
