"I used oil and high speed. Oops."
After wasting quite a few bits drilling on my old jeep, I learned the value of drilling slow. You should be able to watch curls of metal shavings peeling off. I also started using KT drilling and tapping fluid from Murdochs or TSC or similar, and it really helps. Drilling by hand is always tougher as many drills are hard to manage slow speed, and its tough on the motor as it will overheat quickly without air flow for cooling. Using the drill press on the slowest setting whenever possibly is really nice.
