Commercial-PRO Grade!
Im completely blown away by these drill bits. I used the 3/16 size to drill out some thick steel railing posts. These badboys did the whole job in ONE DRILL BIT. Seriously take it from me Ive done auto/handyman work for years- These are steady- well balanced, SHARP bits. I had weight behind them and they had no sign of flex. After 20 uses, my Makita Brushless was still spinning these like butter. I used a center punch for accuracy/ tiny amount of some 3 in 1 oil to keep the metal lubed. Best part is I still have 12 left over. These will be in my tool box for a long time. Definitely will be purchasing more from OWL in the future.
