My lead tech told me to use a 3/8 inch drill bit for a wall fish and I'm glad I listened
Honestly, I was about to use a 1/2 inch bit on this old plaster job in a 1920s house. He said the smaller bit would make less mess and give the coax more room to move. Ngl, I was skeptical, but it went through like butter and the customer's wall looks perfect. Anyone else have a go-to bit size for tricky old walls?

Try a 5/16 bit for really tight spots, it's saved me a few times.

Really feel you on that one. That 5/16 bit saved my bacon last week when I was trying to run coax through an old lath and plaster wall. The stud finder was useless and I ended up drilling blind, that tiny bit just barely cleared the gap. Kind of a lifesaver when you're working in a tight corner behind a built-in cabinet.

That 3/8 bit is the only one I'll touch for plaster. My old boss swore by it for every single wall fish.
