Cleveland C33218 Square End Mill 25/32 in 4 Flute Hss

Product Description

The CLEVELAND C33218 is a 4-flute, single-end square end mill designed for high-demand milling operations in machining environments. Built from high speed steel with a titanium nitride (TiN) finish, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The cutting diameter is 0.7813 inches (25/32 inches), with a 1.875-inch length of cut and a 0.750-inch straight-cylindrical shank that also accepts a Weldon flat drive. Overall length is 4.125 inches. This tool is installed and operated by machinists and tool-and-die professionals on manual mills and CNC machining centers.

The C33218 is suited for milling cast iron, non-ferrous metals, and steel in both roughing and finishing applications. The right-hand cut and right-hand spiral flute geometry with a 30-degree helix angle promotes efficient chip evacuation and stable cutting action. The centercutting design allows for plunge milling as well as standard peripheral and slot milling. This is a regular-length end mill in the Cleveland HG-4C series, appropriate for general-purpose milling in job shop and production environments.

Compatibility

Designed for use in standard end mill holders and Weldon-style set-screw holders accepting a 0.750-inch shank diameter. Suitable for manual knee mills and CNC vertical machining centers. Part of the Cleveland HG-4C series.

Installation Notes

Installation is performed by a machinist using an appropriate end mill holder or collet chuck rated for the 0.750-inch shank diameter. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the end mill. Confirm runout with a dial indicator after installation to avoid premature tool wear or poor surface finish. Follow the machine manufacturer and tooling guidelines for appropriate feed rates and speeds for the workpiece material.
