Which Minicraft thing do you mean?  The  	 	 	 	
Proxxon 28510 Micromot Drill 50/E ?    It is a 40W machine.   I'd
prefer the 100W IB/E (even pricier).   I don't understand why these
tools come with six different sized collets.   I guess a collet is
nothing like a drill chuck.  Maybe somebody can explain it to me.   I
guess these rotary tools are all based on the same motor controller. 
 They all say 5000 to 20000 rpm.   Maybe the same motor too.
I am thinking I might build a levered and counterweighted "drill
press" as Stefan did.
