It is more brittle than say HDPE or UHMW and not as "tough" as Nylon, (which sucks to cut as it wraps around every thing and doesn't form a good chip).

+1, the High Density PolyEthelyne and Ultra High Molecular Weight plastics are nice to machine. It's ok to hold onto also.
Delrin likes to move around and is slippery, but is real easy to machine.
Nylon truly takes a good touch to machine. A good
fast touch.. I used to cut that as fast as the machine would move and it cut pretty good. You almost want to run it at 50% rapid when on an older machine that wont go too fast.. Once it starts to melt, your cutter's basically toast so you gotta really get the heat out with the chips. (It won't usually break right away, but it will load up solid and grow until it can't burn thru the plastic any more, then SNAP!)
