Review on Ultimate Precision: COMOWARE Titanium Twist Drill Bit for Exceptional Results by Leonardo Sandoval

I tested these cutters individually and the first time I used a 1/8 cutter it broke off in a piece of jaw. JAW!? One of the softest and most common types of wood. Not a good sight at all. I've tried bits smaller than 1/8 and they've worked fine, and I've yet to try the larger ones, but if I can't even get through the line to drill a hole without a single click, it might not be a good set. . Unfortunately, probably stay away from them.
