We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "The Medway Handyman"
saying something like:

Not sure if all cordless SDS are slower than mains?

My 12V Bosch definitely is, even when it had newish batteries. It wasn't
rubbish though, just a bit slower and would happily drill several 12mm
holes per charge. It was ex-BT, so had proven its worth up the side of
many houses, I've no doubt.
