Cleveland C63536 4-Flute Ball End Mill
The Cleveland C63536 is a solid carbide ball nose end mill with a 0.25 inch milling diameter and four flutes. It is designed for general-purpose machining of contoured surfaces, slots, and pockets in a variety of materials. The single-end configuration suits CNC and manual milling operations where a ball profile is required. Machinists and maintenance technicians will find it useful for profiling and finishing tasks.
Uncoated Carbide Construction
The tool features an uncoated carbide substrate that provides high hardness and wear resistance at a lower cost than coated alternatives. Its non-coolant-through design means cutting fluid must be supplied externally via flood or mist systems. The four-flute geometry offers a balance of chip evacuation and surface finish quality for general-purpose use. Standard shank dimensions allow it to fit common ER collets and end mill holders without special adapters.
Replaces Worn Ball Nose Cutters
This end mill directly replaces dull or damaged 0.25 inch ball nose tools to restore profiling accuracy and finish quality. The jump is worth it when an existing cutter shows flank wear, chipping, or poor surface finish on radius features. It is not suited for high-feed roughing strategies that demand specialized variable-helix or chipbreaker geometries. Buyers needing extended reach, corner radius profiles, or high-performance coatings for abrasive alloys should select a different tool.

Questions about this item
What shank diameter does the 0.25 in carbide ball end mill use for tool-holder fit?
The cutter has a 0.25 in milling diameter, which typically matches a 0.25 in shank for direct collet or end-mill holder clamping.
What minimum clearance is needed to accommodate the 0.25 in ball-nose profile in a workpiece?
The 0.25 in ball radius requires at least 0.25 in of radial clearance plus tool overhang to reach the contour without holder interference.
How is the uncoated carbide end mill secured in a collet, and what step is often missed?
Insert the shank fully into the collet, tighten the nut to spec, then verify run-out; skipping the run-out check causes premature wear.
