Are you into Dremel (or Dremel like tools) ? Dremel have introduced an EZ Lock system that is bloody terrific. So many accessories now come that are made for the EZ Lock mandrel system. It takes just seconds now to change from one accessory head to another. If your a frequent Dremel user (and aren't all steamers!!!!) next time your shopping for Dremel heads, check out the EZ Lock system.
