Weirdly enough yes I used a CNC router with standard wood bits. It's soft and easy to cut as well as a bit fluffy. The stuff I had had a graduated consistency like chipboard. Fine stuff on the surface with coarser bits in the middle and bigger gaps. I was thinking of using it for casting. It worked but the loose softer texture in the middle meant it was no good for fine details but the texture was interesting sort of roughcast.
