I must say that for the price paid I am more than happy to have spent it. A large hole in masonry without a drill or mandrel would easily cost nearly 2x what I paid for this set with everything including the small carry case. Be prepared not to make a mistake, I used the second largest hole saw drilled through 2 rows of bricks. Punch m18. I think it took a while due to my drill choice but I'm the end she went through. Clean cut! I can't say enough more for this amazing offer. I highly recommend this kit if you are looking for a set like this.
