I am envious of the dentists array of gadgets. Especially their polishing gizmo. I bought GMC DEC003AC 135 Multi Function Rotary Tool and thought that with the extension it should work a treat. Just the soft polishing disk acted like a grinder. I need something small and lightweight for drilling 1/48 and especially for polishing out scribing mistakes.I have looked at the Dremel but is seems like an expensive version of what I have.
