Try posting an ad in the wanted section or tools section on craigslist. I once needed to drill a hole with a 1/2" drill required for the drill bit, but my drill is only 3/8". 1/2" drills are remarkably more expensive and since it was only a one time usage, I posted an ad and got a few people who were willing to help me. I would lend a drill, but I would not lend my drill bits. They can get damaged and worn down.
