Review on 🔩 Hanson 3018002B Cobalt Drill Industrial Set: The Ultimate Precision Power Tool Combo by James Cypert

Good quality drill bit but the case is large and chunky compared to the old Craftsman metal case that came with my last set of drills. I've tried fitting new parts into the old case but they are too big to fit which I don't understand. I haven't used them to pre-drill a threaded hole yet. If they are too far out of tolerance I will revise the rating. Revision: After about a year of use I would say that they are not of very good quality. I have broken 3 bits so far with very limited use. They are extremely brittle. In addition, size tolerances are disabled - too large.
