I just use 1/2" bolts from the hardware store, making sure they're not Grade 8. I don't shear many on the cutter anymore, since the ground I'm cutting has been pretty cleaned up by now of logs, stumps and other hidden gems like cinder blocks. I expect I'll shear more in the future as I've got about 10-15 acres that I've never touched and is pretty tall and overgrown. Probably get to it next year and I'll keep a bunch of bolts on the tractor. I shear more on the post hole digger nowadays.
As for your question on the hole, it would certainly weaken the bolt and is easy enough to do on a drill press, so might give one a little more peace of mind.
However, I can't ever recall hitting something where I thought the shear bolt should have broke and didn't. Most stuff I hit nowadays (limbs and such) just makes a big clatter as it gets run over. :lol:
