Something has gone amiss with the chuck on my ageing budget SDS drill
(Ferm FBH620 from Screwfix many moons ago): tools no longer twist-and-lock.

I've seen fixes online but the prospect of dismantling the chuck doesn't
really appeal.Â* A quick test has revealed that the tool still works
perfectly well as a chisel (which has always been my main need) except
for the inconvenient fact that the bit keeps falling out.

Is there any reason why I shouldn't take my most-often-used chisel bit
and simply stick it in the chuck?Â* A spot of Araldite or even superglue
on the very end ought to hold it, oughtn't it?

Many thanks.


Are you sure this is not caused by a buildup of dried grease and/or
cementatious matter from drilling? May be worth giving the chuck a good
rinse in solvent, followed by your preferred oil spray. May also need to
poke in the hole with a brush and/or jiggle any SDS bit around in the
chuck to help clear it.
