I do now and then. Not for sculpting itself usually, but as a tool for
cutting and grinding. It's a handy thing to have around. It's mainly a
mini versionof the bigger tools I usually use. If you do get one get
one that has an adjustable chuck built in. Some have a screw on kind of
tightener that requires plyers or a little wrench for tightening and
they are a pain. The chuck lets you use a lot of different size tools
without having to fish around for a little part that may or may not fit
your bit. Cool.
