My husband wanted to add a set of hole saws to his workshop so I decided to order them for him. Pocket. My husband said it was easy to put back on but felt the packaging could have been better secured. Please note the plastic envelope did not have foil but it was sent by Revain and I do not wish to call the seller/manufacturer about this. My husband tested three saws and took measurements to see how accurate they were. He was very happy with the accuracy given the price. He tested a 2 1/2", 1 1/2" and 1" saw and then measured with an inexpensive digital caliper. See photos. Each saw was within a 1/16" tolerance and that was it for him acceptable. The set had to come with instructions as the large mandrel has dowel pins, but using a mechanism does not allow the mandrel to be fully tightened to the saw. He said he had never seen a setup like this before. After all, these saws do what they're supposed to do - cut holes. Considering the price and how often he would use the saws, he said he would give the product four stars.
