Hey! I was reading that some people have trouble using dremill (rotary tool) etc to carve bone. There are alot of different tricks to changing and even rebuilding rotary tools.
Dremill are impossible to hold for any mortal! Alot of people change them by adding a handle. Iv seen parts of broom sticks glued to them! :lol: other people will shape their own handles. Im using plastic. Its tricky to mount the handle. I usually duct tape it on and glue it when im sure its in the perfect spot. The handle should be mounted abit closer to the front than 1/2 way and tilting forward. (dermill actuall make some new ones that have handles and are 1/2 the size, expensive tho)
I have used both but Flexi shaft is not good for bone (imo) its only for carving stone. Only because it has alot of torque, and is infamous at losing or surging power. Direct drive has more power and no torque. Just getting the carbide head in correctly is abit of a misson (i have a cheap rotary tool). If its out by 1mm you can hardly tell, except the head jumps and leaves cuts uneaven and rough (better to get a quality dremill instead). Almost all bone tools need some modifying. Using/ adding an extraction system with tools is standard pratice. Also some people add a plastic cover to the front of the dremill to stop dust intake.
Hopefully i'll post some modifyed sanders with extraction later
