Hertel E1050044 Square End Mill 11/16 in 2 Flute Hss

Product Description

The HERTEL E1050044 is a double-end square end mill ground from M7 high speed steel. It carries a 0.6875-inch (11/16 inch) cutting diameter with a 1.3125-inch (1-5/16 inch) length of cut and a 0.750-inch (3/4 inch) shank diameter, yielding a 5.0-inch overall length. The two-flute spiral geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute direction. The uncoated finish is standard for M7 HSS. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual knee mills for slotting, side milling, and profiling operations in ferrous and non-ferrous materials.

This end mill is sized for general-purpose milling work in job shops, maintenance environments, and production cells. The double-end configuration extends tool life by providing a second usable cutting end. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, which is useful for pocketing operations. The regular-length body keeps deflection low in typical depth-of-cut conditions on steel, aluminum, brass, and similar workpiece materials.

Key Features

• Double-end design provides two cutting ends per tool, extending usable life
• Centercutting geometry allows direct plunge milling without a pilot hole
• M7 high speed steel construction offers good toughness and wear resistance
• 30-degree helix angle promotes chip evacuation in slotting and profiling cuts
• Two-flute count leaves open chip gullets for softer and gummy materials
• Uncoated finish compatible with standard cutting fluid and oil mist applications

Compatibility

Designed as an OEM-style replacement or direct substitute for standard 11/16-inch diameter, 3/4-inch shank, double-end square end mills in regular-length configurations used in CNC and manual milling machines accepting straight-shank toolholders.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practice. Secure the shank in a collet chuck, end mill holder, or Weldon-style holder rated for the 3/4-inch shank diameter and torque the setscrew or collet nut per the toolholder manufacturer specification. Power down and lock out the spindle before changing tooling. Confirm runout with a test indicator before beginning production cuts to avoid premature edge wear.
