Just what was needed.
These were regular hole saws, and it was great to have the right sizes, since I don't already own an extensive collection of hole saws. The 2-1/8" hole saw for making a hole in the downspout was slow to cut. The instructions say to go slowly, and all of the other reviews I have read confirm that it is slow to cut. Although it is supposed to be for all types of downspouts, the slowness at cutting my galvanized steel downspout had me wonder if it was the correct type of hole saw. After some research, I learned that more specialized hole saws cost a lot more $$$. So, for making only one or two holes, this is the right hole saw.
