Cleveland C63538 4-Flute Carbide Ball End Mill 0.25 in

What this end mill cuts

The Cleveland C63538 is a solid-carbide ball-nose end mill with a 0.25 in cutting diameter and four flutes. It is uncoated and designed for general-purpose milling in a CNC or manual milling machine. Machinists and small-shop fabricators use it for contouring, profiling and finishing passes in ferrous and non-ferrous metals. It is not suited for high-volume production runs that demand specialised coatings or coolant-through tooling.

How it fits in the spindle

The shank fits standard ER collets or Weldon holders sized for 0.25 in tooling, so it works with most milling machines and router spindles that accept that shank diameter. Four flutes give a smoother finish than two-flute cutters while still clearing chips in lighter cuts. The tool has no internal coolant passages, so external flood or mist coolant must be supplied by the machine. It does not replace roughing cutters or large-diameter tools needed for heavy material removal.

What the uncoated carbide provides

The bare carbide substrate keeps the cutting edges sharp for aluminium, brass and mild steel without the cost of a coating. Being uncoated, it can be resharpened multiple times by a tool-grinding service, extending usable life. No software, collets, holders or coolant accessories are included in the package. Buyers needing coated performance for abrasive alloys or high-temperature alloys will need a different tool.
