Review: Good Quality - Purchased for work. Good quality
Review: Don’t think they’ll last. - This is a good set & comes in really handy when drilling plastic or plasterboard. However after drilling metal trunking for a conduit install most of the coating came off. These are ok for the money but I can’t see them lasting especially if your drilling any metal containment.
