Roughing End Mill for Heavy Material Removal
The Cleveland C31184 is a 4-flute cobalt 8% roughing end mill designed for aggressive stock removal in milling operations. Its coarse pitch geometry breaks chips effectively during heavy cuts. The tool suits machinists and maintenance teams tackling tough alloys or high-volume roughing tasks where rapid material removal takes priority over finish quality.
Upgrade from Standard Finishing End Mills
This rougher replaces general-purpose finishing end mills when the job demands maximum metal removal rates rather than surface finish. The cobalt 8% substrate provides higher hot hardness than high-speed steel, allowing faster feeds in abrasive or work-hardening materials. The jump is worth it when cycle time matters more than a smooth final pass.
Limits of the Weldon Shank Interface
The 5/8 in Weldon flat shank relies on a set-screw holder for retention, which can allow micro-movement under extreme radial loads compared to shrink-fit or hydraulic systems. The uncoated surface offers no thermal barrier, limiting speed in high-heat applications. Non-coolant-through design restricts chip evacuation in deep pockets or blind holes.

Questions about this item
What shank diameter and flat style does the Cleveland C31184 end mill need for the tool holder?
The cutter has a 5/8 in Weldon flat shank; secure it in a matching Weldon holder with the set screw on the flat.
How should the 4-flute cobalt rougher be installed to avoid run-out?
Clean the holder bore, seat the Weldon flat against the set screw, tighten evenly, and check concentricity before cutting.
When will the uncoated cobalt flutes need replacement?
Replace the tool when the coarse pitch edges show visible wear, chipping, or when surface finish degrades beyond tolerance.
