I have this friend with a probelm..... really....:-)
He has trouble with the keyless chucks on his drills (one cordless, one
corded) having the bits slip.
(Craftsman & Black & Decker)
He has tried hand tightening but, the bit still slips. Two drills...
multiple bits/
Could it be technique? Foreighn material on the chuck jaws?
Suggestions please.
Cheap chucks. See if he can find some metal-bodied Jacobs or Rohms.

Grind a couple flat spots on the shank of the drill, don't go overboard,
just enough to give the less expensive chuck something to grab onto.

Rohm are good, but an awful lot of Jacobs' current production is
low-end.
One problem is 1/2" chuck capacity. To get this capacity into a chuck
body that's the size (and price) of a 3/8" chuck, it's necessary to
use a steep angle on the sloping faces. This gives a poor frictional
force to resist slipping loose. Either accept that 1/2" chucks are big
and expensive, or use a 3/8".

Probably he has allowed one or more bits to slip in an under-tightened chuck
before & damage to the face of the jaws has happened, the tool brands you
mention normally come with inexpensive chucks to start with, replace them
with better ones or use hex shank bits in them.....if the keyed chuck has
multiple pilot holes for the key (normally 3) tighten increasingly firmly in
each location, this ensures the chuck is tightened to the max evenly & is
often easier to undo than if all the torque is applied at only one point.
Sorry if I am not clear....but I know what I mean. LOL

Thanks you all for the replys... I suspected that it was a case of
underwhelming quality. I tend to be a bit of a tool snob, so I thought that
I should get a little more input (and a different messenger :-))

Common problem, cheap drills, crappy chucks. Get some hex shank bits
to avoid it. Sorry to be the bearer of bad news...

I have had two B&D keyless chucked drills and they are both crap neither
would hold a bit satisfactorily . I is a shame as I learned as a kid how to
tighten a regular chuck in the same manner with out a chuck key
