Review on High-Performance EZARC Carbide Hole Saw For Cutting Stainless Steel And Sheet Metal - 1-1/8" (29Mm) Hole Cutter by Richard Carroll

Pilot bit is the only reason this didnt get 5 stars from me. Had to punch 12 19mm holes in 16ga stainless. First the bad, started out by drilling pilot holes to make it easier when changing to the tool. First hole and the pilot snapped off. Now for the good, after pulling the pilot and reshaping it on the grinder and drilling pilot holes out the size of the pilot on the tool this little tool went to work and took care of business. 12holes later and the teeth on the cutter look like new and it had performed admirably. Biggest thing to keep in mind, keep the speed slow and just enough pressure to let the cutter do the job without forcing it. Also, use a cutting fluid (I use rapid tap) when cutting a harder material. For the price I would definitely buy it again, but I would HIGHLY recommend drilling the initial hole out to the size of the pilot on the cutter and then just using it as a centering pin, rather than depending on it to cut the pilot hole in harder materials.
