I bought this to cut a 1 1/4 inch diameter hole in a stainless steel sink for a garbage disposal button and it worked perfectly. hole and did it surprisingly quickly. My ONLY complaint, and not even a complaint but more of an observation, would be that after 4 uses the color has just completely faded to the depth I cut. I'm totally fine with paint it's gone all the markings/sizes are engraved anyway but why even paint it is supposed to make the manufacturing process more expensive then disappears after the first day of use and smells funny when flushed into the wood. Color aside this is a fantastic hole saw and if I need it in the future I will definitely be buying a Lenox.
