This is a little of topic but since the shanks are the same could you use a file or grinder to make the indentation on a "normal" bit so it would work with the centrotec chuck. I am just curious because I have so many quick release bits now and that is one of sticking points with buying the C12 for me now. I would like to use the centrotec but don't really want to buy doubles of everything I have because there are a lot of other sanders to be had.
