Hertel E1050028 Square End Mill 7/16 in 2 Flute Hss

Product Description

The HERTEL E1050028 is a double-end, square-profile end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from M7 high speed steel and left uncoated, this tool delivers reliable performance in manual and CNC machining environments. It features a 7/16 inch cutting diameter, a 13/16 inch length of cut, and a 30-degree right-hand spiral flute with centercutting capability. The 1/2 inch shank diameter fits standard end mill holders and collet chucks. Machinists and tool-room operators use this style of end mill for slotting, profiling, and plunge cuts where HSS tooling is preferred over carbide.

This end mill suits light-to-medium duty milling operations in job shops, maintenance environments, and tool rooms. The double-end design extends tool life by providing two usable cutting ends before the tool is retired. The centercutting geometry allows direct plunge entry into a workpiece without a pre-drilled pilot hole. Its regular length designation keeps the tool rigid under side-load cutting conditions, making it appropriate for conventional milling on knee mills, bed mills, and CNC machining centers running moderate feed and speed parameters.

Key Features

• Double-end design provides two cutting ends for extended tool value
• Centercutting geometry allows direct plunge milling without a pilot hole
• 30-degree right-hand helix promotes efficient chip evacuation during cuts
• M7 high speed steel construction suited for general-purpose ferrous and non-ferrous milling
• Uncoated finish maintains sharp edge geometry without coating-induced edge buildup
• Right-hand cut and right-hand flute for use in standard spindle rotation

Compatibility

Designed as a standard replacement or stock end mill for machine shops using 1/2 inch end mill holders or ER-style collet chucks requiring a 7/16 inch cutting diameter in the regular-length class.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine spindle fully stopped and the machine locked out per shop safety procedures. Verify that the collet or tool holder is clean and free of chips before seating the shank. Torque the retention hardware per the tool holder manufacturer specifications. Confirm correct spindle direction and feed rate before initiating a cut.
