I recently received this AZ size drill bit set. I haven't used any of these bits yet. But I also got a set of wire size drill bits from the same manufacturer and used a drill bit that worked great. I assume this drill set will work just as well.
I bought this item and another set for my husband. He enjoys making small house projects that require a lot of drilling. Lately he's been working on deck. This set is really strong and works great on all materials including wood, plastic and even steel. Powerful tools. He loves it.JL
