Hertel E1050040 Square End Mill 5/8 in 2 Flute Hss

Product Description

The HERTEL E1050040 is a double-end, square-profile end mill designed for general-purpose milling operations in metal fabrication and machining environments. It is manufactured from M7 high speed steel and left uncoated, making it well suited for conventional milling in ferrous and non-ferrous materials where heat buildup is managed through appropriate feeds and speeds. The tool features a 5/8 inch mill diameter, a 1-1/8 inch length of cut, and a 4-1/2 inch overall length. With a 30-degree helix angle and centercutting capability, it can be used for plunge entry as well as peripheral and slot milling. Machinists and tool-and-die professionals are the primary users of this tooling.

This end mill is appropriate for use in manual knee mills, CNC machining centers, and bridgeport-style machines where a 5/8 inch straight shank collet or end mill holder is available. The double-end configuration provides two usable cutting ends, extending tool service life before replacement is required. It is commonly applied in job shop environments for profiling, slotting, and face milling operations on steel, aluminum, brass, and similar workpiece materials. The regular-length classification means this tool fits standard reach applications without extended-reach toolholding.

Key Features

• M7 high speed steel construction for toughness and wear resistance in general machining
• Double-end design provides two cutting ends per tool
• 30-degree helix angle promotes smooth chip evacuation and stable cutting action
• Centercutting geometry allows direct plunge entry into workpiece material
• Right-hand cut and right-hand spiral flute configuration for standard spindle rotation
• Uncoated finish suitable for use with cutting fluid in a wide range of materials

Compatibility

Designed as an OEM-style replacement or direct-use tooling for any milling machine or machining center accepting a 5/8 inch straight shank end mill holder or collet chuck.

Installation Notes

Installation is performed by a qualified machinist following standard toolholding procedures. The shank should be fully seated and secured in a clean, undamaged collet or end mill holder before operation. Verify spindle runout is within acceptable limits before engaging the workpiece, as excessive runout accelerates tool wear and degrades surface finish. Always follow applicable machine guarding requirements and shop safety protocols when changing or setting tooling.
