If you do want to drill the stainless steel calipers, the carbide drills
from Drill City will do the job.

I recently adapted 6" digital calipers to my lathe and mill to give be
digital readouts, and I drilled the caliper bodies with these drill bits.

Go easy though. The drills are very sharp and hold their edge well, but they
are brittle.
