Review on 🔩 54CT-3-3 Carbide Tipped Hole Drill by Robert Blanton

Ordered to drill through a steel I-beam. Shocked. I even used my cordless drill (DeWalt 18v) and did it with a battery. Just use a low speed and make sure it is perpendicular to the drilling surface or you will break the pilot bit. And no oil! I did it first and he started smoking like a bastard. Dry!
