I just bought a corded hammer drill from Homebase, brand PBX (their

while you all have complete hysterics) It's a keyless chuck where you
pull the rear sleeve of chuck back and then turn front sleeve to
tighten/loosen the chuck.

The rear sleeve seems to move back, although only slightly and the
front sleeve only turns a half - 3/4 turn which barely tightens the
chuck at all.

I know this is absolutely stupid but I am completely baffled and
embarassed to have to ask for help.

Please someone put me out of my misery!

Are you sure it's a hammer drill and not an SDS drill. SDS drills need
special bits with fluted ends - which can be inserted or removed after
sliding back the collar on the equivalent of the chuck. Is this what you've
got?
