Spent a whole afternoon on a single coax run in an old Seattle apartment

The wall cavity was packed with old plaster and lathe, and I hit a fire block I didn't expect. What should have been a 30 minute job turned into a 3 hour fight with a flex bit and a lot of patience. Anyone have a better trick for dealing with those solid old fire blocks in pre-war buildings?

My old building in Portland had the same thing. I used a long flex bit and a lot of fish tape to finally get past it.

A heat gun on the pipe worked for me when fish tape failed.
