My mag drill arrived and was packaged very well. Everything about the drill works well except for the quick change chuck. It is easy to insert and remove the cutters before you use them. After drilling just one hole, the bits become stuck. The only way I could remove the cutters was to disassemble the quick change chuck, clamp the cutter in my vice, and beat on the drill with a hammer. I tried all the bits that were included and every single one suffered this issue, so it has to be the chucks fault and renders the entire drill useless.
This issue also reviled how difficult is is to get a refund. Customer support was haggling with me about how much to refund me. I had to ask for a full refund 4 separate times before they final granted it.
My advice to you is do not buy this particular mag drill, buy the cheapest one with the standard set screws to hold in the cutters. also, you must be comfortable with not getting a refund. They make it very difficult and there are no guarantees.
