Cleveland C41043 Square End Mill 1/8 in 2 Flute Hss HMD-2

Product Description

The CLEVELAND C41043 is a double-end, two-flute square end mill designed for precision milling operations in ferrous and non-ferrous materials. Manufactured from high speed steel (HSS), it features a 1/8 inch cutting diameter, a 3/8 inch length of cut, and a 30-degree helix angle that promotes efficient chip evacuation. The bright, uncoated finish is standard for general-purpose HSS tooling. With a straight-cylindrical shank measuring 3/16 inch in diameter and a 2-1/4 inch overall length, this is a regular-length tool suited for close-tolerance work on manual mills, CNC machining centers, and benchtop equipment.

The C41043 is built for cutting cast iron, non-ferrous metals, and steel in light-to-moderate material removal applications. Its double-end configuration extends tool life by providing two usable cutting ends before replacement. The right-hand cut and right-hand flute direction make it compatible with standard spindle rotation. Typical applications include slotting, profiling, and peripheral milling in job shop, toolroom, and production environments where HSS tooling is preferred over carbide for its toughness and regrindability.

Key Features

• Double-end design delivers two cutting ends per tool, extending service life
• High speed steel construction provides toughness and resistance to chipping under interrupted cuts
• 30-degree right-hand helix promotes smooth chip flow and reduces cutting forces
• Center-cutting geometry allows plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for general-purpose milling across multiple material types
• Straight-cylindrical shank fits standard ER collets and end mill holders

Compatibility

Designed as a regular-length HSS square end mill compatible with standard end mill holders and ER collet chucks accepting a 3/16 inch shank diameter. Primary workpiece materials include cast iron, non-ferrous metals, and steel.

Installation Notes

Installation should be performed by a qualified machinist familiar with rotating cutting tool safety. Ensure the spindle is fully powered down and locked before securing or changing the tool in the holder. Use an appropriate collet or end mill holder rated for the 3/16 inch shank diameter and torque the retention nut per the holder manufacturer's specification. Inspect the cutting edges for chips or wear before each use, and do not exceed the recommended speeds and feeds for HSS tooling in the workpiece material being cut.
