Hertel E1051044 Square End Mill 11/16 in 4 Flute Hss

Product Description

The HERTEL E1051044 is a double-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous metals. Manufactured from M7 high speed steel (HSS) with no coating applied, it delivers consistent cutting performance across a range of conventional machining setups. The tool measures 11/16 inch (0.6875 inch) in diameter with a 1-5/8 inch length of cut and a 3/4 inch shank diameter. Overall length is 5-5/8 inches. The four-flute, 30-degree right-hand spiral configuration promotes chip evacuation and surface finish quality in standard milling applications. Machinists and tool-and-die professionals are the primary installers of this tooling.

This end mill is suited for use in vertical milling machines, knee mills, and CNC machining centers where moderate material removal and profile milling are required. The double-end design extends usable tool life by providing a second cutting end when the first shows wear. The regular-length configuration fits standard toolholders and collet systems without the need for extended-reach setups. Typical applications include slotting, side milling, and profiling cuts in steel, cast iron, and similar materials at conventional cutting speeds appropriate for HSS tooling.

Key Features

• Double-end design provides two usable cutting ends per tool
• M7 high speed steel construction for toughness in interrupted cuts and general milling
• 30-degree right-hand helix spiral flute promotes chip flow and reduces cutting forces
• 4-flute configuration balances material removal rate with surface finish quality
• Uncoated finish suits regrinding and use with conventional cutting fluids
• Non-centercutting geometry — not designed for direct plunge entry

Compatibility

Designed as a standard double-end square end mill for use in 3/4 inch collets, end mill holders, or Weldon-style side-lock holders on conventional and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder specifications. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder to the minimum engagement depth recommended for the holder type. This tool is not centercutting and should not be used for direct plunge cuts without pre-drilling or ramping entry.
