Both of the bits that came with this broke within the first use! Do not recommend this whatsoever. I was trying to drill a hole through some thin metal on an Ikea cabinet. This product does not work as advertised. Don't waste your money

So this was the second Chuck that I ordered trying to get my project complete. This one did not fall apart and was barely enough to let me finish getting all those holes in that iron. This tool outlived the drill that I was using. Burnt it up. What are you going to do. This is worth your money.
