Hertel E1031044 Square End Mill 11/16 in 4 Flute Hss

Product Description

The HERTEL E1031044 is a 4-flute square end mill designed for general-purpose milling operations in ferrous and non-ferrous metals. Manufactured from M7 high speed steel, this tool delivers consistent performance in profiling, slotting, and peripheral milling applications. It features an 11/16-inch cutting diameter with a 1-5/8-inch length of cut and a 5/8-inch shank diameter, making it a regular-length tool suited for standard reach milling tasks. The 30-degree spiral helix promotes efficient chip evacuation, and the right-hand cut with right-hand flute geometry is the industry-standard configuration for conventional milling setups. This end mill is uncoated and non-centercutting.

This end mill is appropriate for manual mills, CNC machining centers, and knee mills where a standard-length HSS tool is specified. Its regular length classification and 3-3/4-inch overall length make it a practical choice for general shop work including face profiling, side milling, and slot milling in steel, cast iron, aluminum, and similar materials. It is typically installed and used by machinists and tooling professionals in job shops, maintenance facilities, and production environments.

Key Features

• M7 high speed steel construction for toughness in interrupted and general-purpose cuts
• 4-flute design balances chip clearance with surface finish quality
• 30-degree helix angle supports smooth chip flow and reduced cutting forces
• Right-hand cut and right-hand flute geometry for standard spindle configurations
• Spiral flute style with uncoated finish suitable for use with cutting fluids
• Non-centercutting — not designed for direct plunge operations

Compatibility

Designed as a standard-shank square end mill compatible with 5/8-inch collets, end mill holders, and milling chucks on conventional and CNC milling machines accepting that shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding practices. Ensure the machine spindle is fully stopped and locked before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and secure with appropriate torque per the toolholder manufacturer guidelines. Confirm runout with a dial indicator before beginning a cut, particularly for tight-tolerance work.
