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 ...
