I wish the Centrotec chuck was as good as the Wiha centrofix bit holder (71480), also found on the newer Festool screwdriver in the 98-piece installer set. That bit holder accepts both regular 1/4" and Centrotec bits and holds both tighter than even a Centrotec bit/drill in a Festool Centrotec chuck. With the Wiha, there is zero wobble, and with the Festool centrotec chuck, there is just a slight wobble. Right now one is limited to using this bit holder with a jacobs chuck. Would have been really nice if somehow someone could design a chuck with the grabbing power and versatility of the Wiha, but with the short length of the Festool chuck.
