Another question arises though (in my thinking about those very hard but
rather thin panels in my garage): is an SDS going to run the risk of
cracking concrete rather than drilling it?
Why do there seem to be no thin diamond drill bits for these hard but
delicate jobs?

You would need to be very gentle with an SDS on a panel garage.

Thought so: *back to hanging things from bamboo threaded through the spare
bolt holes then!

You can get mortar raking bits for angle grinders that can be used
like a short drill bit. Theyre abrasive coated, TC IIRC, so one ought
to do the job if you take care not to let it wander sideways.

I've drilled asbestos panels using a no-hammer drill years ago, it was
slow but did work. I've a feeling it was done with a twist drill, not
a masonry bit.
