Cleveland C42067 Square End Mill 13/32 in 2 Flute Hss

Product Description

The CLEVELAND C42067 is a double-end square end mill designed for material removal in milling operations across ferrous and non-ferrous metals. It is manufactured from high speed steel (HSS) with a bright, uncoated finish and features a 30-degree helix angle for efficient chip evacuation. The tool carries a 13/32 inch (0.4063 inch) cutting diameter, a 13/16 inch (0.8125 inch) length of cut, and an overall length of 4-1/8 inches. It is center-cutting with right-hand cutting and right-hand flute direction, making it suitable for both plunge and peripheral milling. Machinists and tool and die professionals are the primary installers of this end mill.

The C42067 is well suited for general-purpose milling on cast iron, non-ferrous metals, and steel. Its double-end configuration extends tool life by providing two usable cutting ends, making it a practical choice for job shops, maintenance departments, and production environments running manual or CNC milling machines. The 1/2 inch straight-cylindrical shank with Weldon flat accommodates standard end mill holders and milling chucks. It belongs to the Cleveland HD-2 series, which targets heavy-duty cutting applications in short to regular length configurations.

Compatibility

Designed as an OEM-style replacement and general-purpose fit for standard 1/2 inch end mill holders and milling chucks used on manual knee mills and CNC machining centers. Primary workpiece materials are cast iron, non-ferrous metals, and steel.

Installation Notes

Installation is performed by machinists using standard end mill holders or Weldon-style set-screw chucks. Ensure the machine spindle is fully powered down and locked before changing tooling. Confirm the Weldon flat is aligned with the set screw before torquing the holder. Follow your machine tool manufacturer guidelines for runout tolerance and holder engagement depth.
