A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

For 3D shapes like the yoyo project below, a 1/8" or 1/16" ball end mill produces the smoothest contours. For best results, keep a set of end mills specifically for Delrin and other plastics, and never use them to cut metal or PCBs. This allows for increased milling speeds and a better finish.

Ball end mills. A popular alternative cutter for engraving in plastic and metal is to use a small ball end mill, something in the range of 1/32". The benefit to a ball end mill is that the lack of a sharp tip makes them very durable and they're typically ground with 24 spiral flutes. The downside is that the engraving may not be quite as sharp ...
