I received this with FULL expectation of using it to drill a hole or two because I knew it wouldn't last anymore and I was in. I gave it 5 stars because it's so reasonably priced and it had the two sizes I needed and still have a few sizes left that I could poke some holes with in the future. I used 5" to make a hole out of 1/2" chipboard and it warned visibly after the first hole. I think he could make an extra hole or two in the 1/2" board. I used 6" to make a hole out of 1 2" drywall and then 3/4" particle board. He struggled terribly over 3/4 inch. I'm guessing the friction knocked out more wood than the saw, but it still went through! path in the forest! I had very low expectations and it worked! I am not disappointed with this purchase!
