disappointed. 1 small drill broke on first use, 2 others became blunt while drilling a 5/16 cast aluminum screw. Drill no better or longer than cheap Chinese drills. I'm frustrated, paid for superior quality and didn't get it.
Tired of missing out on drill sets? And the missing size is usually what you need, according to Murphy, right? Well, here is the complete set. All the dimensions you need in one place. The certainty of always having the right racquet size is worth the money.
Drill bits cut well and cut evenly between the three blades. What I don't like is the difficulty in reading the second and third row sizes. It would be better if they mark the second row the same as the first and mark the third row at the back where it is open. Or set it up to roll over each row and tokenize each row.
