Hertel E1033040 Square End Mill 5/8 in 2 Flute Hss

Product Description

The HERTEL E1033040 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M7 grade high speed steel with a bright, uncoated finish, this tool handles slotting, peripheral milling, and profiling on a range of ferrous and non-ferrous materials. It features a 5/8 inch diameter cutting face, a 1-3/8 inch length of cut, and a 4-5/8 inch overall length. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and reduces heat buildup during cuts. This tool is installed and operated by machinists and tool-and-die professionals using standard milling machines or CNC machining centers.

This end mill is suited for use in job shops, production machining cells, and tool rooms. Its centercutting capability allows it to plunge directly into a workpiece, making it useful for both drilling entries and lateral milling passes. The extended reach design, with a 2-3/4 inch reach length, allows access to deeper features and stepped cavities without requiring a special-purpose extended-reach holder. The 5/8 inch shank diameter fits directly into standard ER and R8 collet systems commonly used in vertical milling setups.

Key Features

• M7 high speed steel construction provides good wear resistance and toughness in interrupted cuts
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 30-degree right-hand helix promotes smooth chip flow and reduces cutting forces
• Extended reach of 2-3/4 inches provides access to deeper pockets and stepped features
• Bright uncoated finish is compatible with a wide range of cutting fluids and coolants
• 2-flute configuration maximizes chip clearance in slotting and deep pocket applications

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for standard vertical milling machines and CNC machining centers accepting a 5/8 inch shank diameter end mill.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder to the recommended engagement depth to prevent pullout under load. Verify runout with a dial indicator after clamping before beginning a cut.
