I have a set of Mac drill bits right now. They have lasted a few years but, I recently started a mechanic job working on semis and trailers. I've used my drill bits more in the last 3 months then i have in the last 3 years. That being said, I'm running out of drill bits due to most of them breaking. What is a good brand of strong longer lasting drill bits to buy?
