Cleveland C80423 5-Flute Carbide Square End Mill

Cleveland C80423 5-Flute Square End Mill

The Cleveland C80423 is a 5-flute carbide square end mill built for high-performance milling in steel. Its TiAlN coating supports longer tool life and higher cutting speeds. The straight shank design fits standard collets and holders. This new tool suits machinists and shops running production or prototype work in ferrous materials.

Check shank diameter and holder compatibility

Verify that your tool holder or collet accepts a 3/16 in shank before ordering. The cutter has a 0.1875 in milling diameter and a 0.5625 in length of cut, so confirm your workpiece clearance and machine travel can accommodate these dimensions. The tool is non-coolant-through, so external flood or mist coolant must be available if your process requires it. Ensure your spindle speed and feed rate capabilities match carbide tooling parameters for steel.

Replaces worn or lower-flute carbide end mills

This cutter upgrades from 2-flute or 3-flute carbide end mills when chip evacuation and finish quality in steel become limiting factors. The 5-flute geometry increases feed rates and reduces chatter in profile and finishing passes. The jump is worth it when cycle time, surface finish or tool-change frequency justify the step up in flute count. It does not serve applications needing coolant-through delivery or larger diameter roughing cuts.
