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 ...

Ball nosed cutters: slow nose speed. The biggest challenge with ball nosed end mills of various kinds is slow nose speed. As you get closer to the tip, the diameter on the ball gets smaller and smaller, finally going to zero. As a result, the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.
