Hertel E1030905 Square End Mill 3/4 in 2 Flute Hss

Product Description

The HERTEL E1030905 is a single-end, square-profile end mill designed for general-purpose milling operations in ferrous and non-ferrous metals. Built from M7 High Speed Steel with a bright/uncoated finish, it delivers reliable performance in slotting, profiling, and peripheral milling applications. The 3/4-inch cutting diameter is paired with a 1-5/16-inch length of cut and a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. With a 5/8-inch shank diameter and a 3-7/16-inch overall length, this end mill fits standard milling chucks and collet holders. Installation is handled by machinists and tool-and-die technicians in shop and field machining setups.

This end mill is suited for use in vertical and horizontal knee mills, CNC machining centers, and manual milling machines where a standard-reach, two-flute geometry is preferred. The two-flute configuration provides larger gullet volume for improved chip clearance, making it well-suited for softer materials and applications requiring heavier chip loads. The right-hand cut and right-hand spiral flute direction are consistent with conventional milling setups. Centercutting capability allows direct plunge entry into the workpiece without a pre-drilled hole.

Key Features

• M7 High Speed Steel construction for toughness and wear resistance in general milling
• 3/4-inch mill diameter with 1-5/16-inch length of cut for standard-depth slotting and profiling
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Two-flute spiral design maximizes chip clearance in softer or gummy materials
• Centercutting geometry allows direct plunge milling without pre-drilling
• Bright/uncoated finish suitable for use with cutting fluid or dry in appropriate materials

Compatibility

Designed as a standard-shank replacement end mill compatible with 5/8-inch collets, milling chucks, and side-lock holders used in manual mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before inserting or removing the end mill from the holder. Ensure the shank is fully seated and the collet or chuck is torqued to tool-holder manufacturer specifications. Inspect the cutting edges for chips or wear before each use and replace the tool if edge integrity is compromised.
