Hertel E1050008 Square End Mill 1/8 in 2 Flute Hss

Product Description

The HERTEL E1050008 is a double-end square end mill designed for general-purpose milling operations in metal, composites, and plastics. Manufactured from M7 high speed steel, this tool features a 0.125-inch cutting diameter, a 0.375-inch length of cut, and a 30-degree helix angle with spiral fluting. The right-hand cut, right-hand flute geometry paired with centercutting capability allows both peripheral and plunge milling. At 3.0625 inches overall length with a 0.375-inch shank diameter, it fits standard milling chucks and collet holders used in vertical and horizontal machining setups. Machinists and toolroom operators are the primary users of this tool.

This end mill is suited for light to medium material removal on ferrous and non-ferrous workpieces in job shop, toolroom, and maintenance machining environments. The double-end configuration provides two usable cutting ends, extending tool life between resharpening cycles. The uncoated M7 HSS construction makes it a practical choice when cutting softer steels, aluminum, brass, and plastics where carbide tooling is not required. It is commonly used on manual knee mills and CNC machining centers operating at appropriate surface speeds for HSS tooling.

Key Features

• Double-end design provides two cutting ends for extended tool life
• Centercutting geometry enables plunge and slot milling without a pre-drilled hole
• 30-degree helix angle promotes chip evacuation and smooth cutting action
• M7 high speed steel construction offers toughness and wear resistance for general machining
• Right-hand cut and right-hand spiral flute for standard milling machine spindle direction
• Uncoated finish suitable for use with cutting fluids on a wide range of workpiece materials

Compatibility

Designed as a standard 0.375-inch shank square end mill compatible with collet chucks, end mill holders, and milling machine spindles accepting 3/8-inch shank tooling.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and power locked out. Ensure the collet or end mill holder is clean and free of chips before seating the shank. Tighten the holder to the tool manufacturer's recommended clamping specification for the holder type in use. Verify runout with a dial indicator before beginning a cut, particularly for tight-tolerance work.
