Hertel E1052028 Square End Mill 7/16 in 3 Flute Hss

Product Description

The HERTEL E1052028 is a double-end, square-profile end mill designed for general-purpose milling operations in metal fabrication and machining environments. It measures 7/16 inches (0.4375 inches) in diameter with a 1-inch length of cut and a 4-1/8-inch overall length. Manufactured from M7 high speed steel with a bright, uncoated finish, this tool is well suited for shops running lower-speed operations where HSS tooling is preferred over carbide. A 1/2-inch shank diameter fits standard collet chucks and end mill holders. Installation and use are handled by machinists and CNC or manual mill operators.

This end mill is built for right-hand cutting and right-hand flute direction with a 30-degree helix angle and three spiral flutes. The double-end configuration provides two usable cutting ends, extending tool life per unit. It is centercutting, which allows plunge cuts as well as conventional peripheral milling passes. Typical applications include slotting, profiling, and shoulder milling in ferrous and non-ferrous materials. The regular length classification makes it a standard fit for most bridgeport-style and CNC vertical milling setups where reach is not a limiting factor.

Key Features

• M7 high speed steel construction for durability in general-purpose milling
• Double-end design provides two cutting ends per tool
• Centercutting geometry allows direct plunge entry without pre-drilling
• 30-degree helix angle with three spiral flutes for efficient chip evacuation
• Bright, uncoated finish suitable for use with standard cutting fluids
• Right-hand cut and right-hand flute for compatibility with standard mill spindles

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for vertical mills, knee mills, and CNC machining centers accepting a 1/2-inch straight shank end mill holder or collet.

Installation Notes

Installation is performed by machinists using a standard end mill holder or ER-style collet chuck rated for 1/2-inch shank tooling. Always de-energize and lock out the spindle drive before changing tooling. Verify tool runout with a dial indicator after mounting and before cutting. Follow shop-standard feeds, speeds, and coolant practices for M7 HSS tooling in your specific material.
