Sadly this doesn't seem to be the case on these drills. No screw, I'm wondering if it's the sort where an allen key needs to be inserted, tightened and then bashed (as I've read in other places)
Anybody know how to remove the keyless chuck on the Bosch PSB family of drills? I want to replace the chuck on a PSB750 RCE and can't work out how to remove the chuck.
