Cleveland C41070 Square End Mill 1/16 in 2 Flute Hss

Product Description

The CLEVELAND C41070 is a double-end, square-profile end mill designed for precision milling in metalworking and machining applications. Built from high speed steel (HSS) with a bright/uncoated finish, it measures 0.0625 inches in diameter with a 0.2188-inch length of cut and a 2.5-inch overall length. The 3/16-inch straight shank seats securely in standard collets or chucks. With two spiral flutes at a 30-degree helix angle and a centercutting geometry, this tool removes material efficiently while maintaining edge integrity. Licensed machinists and tool-and-die professionals are the primary users of this series.

The C41070 belongs to the Cleveland HMD-2 long series and is suited for slot milling, profiling, and light contouring in cast iron, aluminum and non-ferrous metals, and steel. Its double-end configuration extends tool life by providing two usable cutting ends per tool, making it a practical choice for production shops and job shops running high-mix, low-volume work. The long series length accommodates moderate-depth features where a standard-length end mill would not reach.

Key Features

• Double-end design provides two cutting ends per tool for extended service life
• 0.0625-inch (1/16 inch) cutting diameter with 0.2188-inch (7/32 inch) length of cut
• High speed steel construction handles cast iron, aluminum, non-ferrous metals, and steel
• 30-degree helix spiral flute promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece material
• Bright/uncoated finish — no coating to mask geometry; suitable for re-sharpening

Compatibility

Designed as an OEM-style replacement and standard production end mill for use in CNC machining centers, knee mills, and manual milling machines accepting a 3/16-inch straight shank. Primary workpiece materials include cast iron, aluminum and non-ferrous alloys, and steel.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Power down and lock out the spindle before inserting or removing the tool. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the machine manufacturer's specification. Inspect flute condition and shank runout before each use; a damaged or deflected end mill at this diameter is subject to breakage under load.
