Cleveland C60621 3-Flute Carbide Square End Mill .25 in pneumatic accessory

0.25-inch Carbide End Mill

The Cleveland C60621 is a 3-flute square end mill designed for high-performance milling in aluminium. Its uncoated carbide construction suits machinists and fabricators who need sharp edge retention in non-ferrous materials. The 0.25 inch diameter and 0.75 inch length of cut handle profiling and slotting tasks in a single pass. It fits standard 1/4 inch shank holders on milling machines or routers.

Check Shank And Toolholder Fit

Verify that your machine spindle or collet accepts a 1/4 inch shank before ordering. The tool has no coolant-through channels, so external flood or mist coolant must reach the cutting zone if your application requires it. Ensure the 2-1/2 inch overall length clears your workpiece and fixture without interference. Confirm the material being cut is compatible with uncoated carbide geometry.

Build Integration And Clearance

The straight shank mounts directly into ER collets, Weldon flats or shrink-fit holders without adapters. Its 0.75 inch flute length frees up axial space for shallow pockets or thin-wall parts. The uncoated surface reduces built-up edge in aluminium, preserving finish quality without coating delamination. The 3-flute design balances chip evacuation and rigidity for stable profiling cuts.
