Got a torch, but even after heating for a while a hammer didn't budge it, although i'm not a metal worker by any means!
Ended up just drilling them out, although seem to have destroyed a 3mm HSS bit on only 6 rivets. Disappointed by this Bosch set i bought. Was supposed to be a "professional" kit to avoid going to the storage unit to dig mine out, but they've been worse than the cheap ones i've had. Been taking it really slow and easy too with plenty of breaks to cool the tip.
Might have to pick up a few cheap bits for the other seat!
