Hertel E1043956 Square End Mill 7/8 Inch 3 Flute Hss

Product Description

The HERTEL E1043956 is a square end mill designed for general-purpose milling operations in metalworking and machining environments. Built from M7 high speed steel, this tool features a 7/8-inch cutting diameter, a 1-7/8-inch length of cut, and a 30-degree helix angle with three spiral flutes for efficient chip evacuation. It is a right-hand cut, right-hand flute, centercutting design, making it capable of both peripheral and plunge milling. The uncoated finish suits applications where lubrication or coolant is readily available. Machinists and tool-and-die professionals rely on this style of end mill for slotting, profiling, and shoulder milling on ferrous and non-ferrous materials.

This end mill is suited for use in manual mills and CNC machining centers handling light to medium-duty stock removal. Its regular-length geometry and matched 7/8-inch shank diameter provide rigid tool holding in standard ER collets, end mill holders, or Weldon-style set-screw holders. Typical applications include slot milling, side milling, and contouring in steel, cast iron, aluminum, and similar machinable alloys. The centercutting capability allows the operator to plunge directly into the workpiece without a pre-drilled pilot hole.

Key Features

• M7 high speed steel construction for durability in general machining applications
• Three spiral flutes with 30-degree helix angle for balanced cutting action and chip flow
• Centercutting design enables direct plunge entry into the workpiece
• Right-hand cut and right-hand flute configuration matches standard spindle rotation
• Uncoated finish compatible with flood coolant and cutting oil use
• Matched 7/8-inch shank and cutter diameter for consistent tool-holder fitment

Compatibility

Designed as a standard-shank square end mill suitable for use in any machine tool spindle accepting a 7/8-inch shank via collet chuck, end mill holder, or set-screw holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify proper shank insertion depth and torque the holder to the tool manufacturer's recommendation for the holder style in use. Inspect the cutting edges for chips or wear before each use, and confirm the workpiece is securely fixtured before engaging the cut.
