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.

Questions about this item
How deep can I cut with the 0.25 in diameter before the tool deflects?
The 0.25 in diameter carbide body provides high rigidity for shallow profiling passes, but maximum depth per pass depends on your machine rigidity and the material being cut.
Does the uncoated carbide generate excessive heat during long runs in steel?
Uncoated carbide runs hotter than coated alternatives in steel; use flood coolant or air blast to manage temperatures and prevent built-up edge on the flutes.
What shank size does the C63538 have so I know if it fits my collets?
The shank diameter matches the 0.25 in cutting diameter, so it fits standard 1/4 in ER collets, Weldon flats or shrink-fit holders directly.
