Review on 🔩 High-Performance M35 Cobalt Drill Bit by Drill America by Reginald Hamilton

Excellent drill bits, very strong and stay sharp. I've used them for a ton of drilling in mild steel, aluminum, and wood with almost no problems (except breaking a small piece due to my own misalignment). I would definitely buy cobalt drills again but with this set I doubt I will have to buy them for long. They are long enough that the point shifts and may not be centered.
