Half-Inch Ball Nose Double-End Mill
The Cleveland C42199 is a .5 in diameter ball nose end mill with two flutes and cutting ends on both sides. It is made from high speed steel with a bright, uncoated finish. Machinists choose it for contouring, profiling and pocketing operations where a rounded corner radius is required.
Fits Standard Half-Inch Tool Holders
The .5 in shank diameter fits directly into common collets, end mill holders and milling chucks without adapters. Having two cutting ends on a single tool body reduces the number of tool changes and frees up carousel slots in the machine. The non-coolant-through design means no internal coolant passages are needed in the spindle or holder.
HSS Handles Sustained Heat Without Chipping
High speed steel retains hardness at the temperatures reached during longer cuts, so the edges resist softening better than carbon steel. The uncoated surface avoids coating delamination when the tool dwells in a cut or runs dry. Builders who need coated performance for high-speed production or abrasive alloys should select a different tool.

Questions about this item
How long does the .5 in ball nose hold its edge under continuous milling?
High-speed steel construction resists wear during extended cuts, though exact tool-life depends on material, speed and feed settings.
Does the uncoated HSS run hot or noisy when the spindle runs all day?
The bright finish transfers heat directly to chips and coolant, so temperatures stay manageable with proper flood or mist cooling; noise is typical for HSS end mills.
What shank size or holder does the C42199 require to mount in my machine?
The double-end design uses a standard .5 in shank diameter, so it fits common ER, Weldon or mill-chuck collets without an adapter.
