Hello,

I have a 1100W corded Titian hammer drill I bought from Screwfix a few years ago. The keyed chuck does not hold drill bits properly now when drilling through anything a bit tough. I think this is due to wear of the chuck. I believe that generic spare chucks for drills are available, so I tried to remove the old chuck as a first step towards fixing the drill. I seemed to remember reading that to remove a chuck one opens it all the way, which reveals the retaining grub-screw. I can not find such a grub-screw for this chuck.

I have looked at a couple of other, smaller, drills I have and can easily find their screw. But for the Titian, nothing. I did try to unscrew the body of the drill to see if the chuck could be removed that way, and count myself very, very, lucky I only opened it slightly and was able to reassemble it again (so many cogs!).

Does anyone have any suggestions about the chuck?

TIA
