A Dremel is perfect for the uses you describe PROVIDED you slow the speed waaaay down. I use an older non battery Dremel and a tungsten twist router, both straight and with a curved tip. The Dremel plugs into a Dremel rheostat which reduces the rpm's to the point I can stop the spinning by putting my finger against the bit. I also use a foot pedal on/off switch, so I don't have to put down someting to turn off the Dremel.
I use this for drilling holes, and high speed will leave you with an embedded drill bit so quick! But the real forte is grinding away. I don't use the sanding discs or drums, too rough. These bits can really remove material but with a light touch can result in a really smooth finish.
Grinding resin will create clouds of toxic dust. So do this outside and with a very good mask, preferrably with a fan blowing the dust away form you! Try doing it "wet" so you get mush and not dust. Just a little grinding without protection leaves my nose feeling strange.
I've used one of the tungsten bits for over 30 years and it still works fine. In its early days our son used it to grind out the engine intake ports of his go kart!
The portable model may be attractive for size and no cord, but controlling the speed/rpm is critical for success. So I'd strongly recommend a Dremel PLUS a separate speed control. And a SEPARATE speed control, not one built into the unit.
Have fun...it's a great tool!
