This was used on a SS free standing laundry sink to cut both enlarge a faucet hole and a soap dispenser hole. The new hole was a breeze. The trick for a thin SS sink is to brace under it so you can bear down to cut the hole and it will also steady the work. The hole that was already there but too small to fit my faucet was a bit of a challenge because there was no pilot hole for the drill to steady and run true but it worked out ok anyway. I would recommend to anyone drilling stainless.

No matter how tight I made the set screw to the drill bit, it always worked loose creating wobble and wallowing out my hole. The saw cuts well, so I intend to spot weld or epoxy the drill bit in place.

Had to cut hole in 3/4 aluminum plate. Did a great job and no sanding needed

Made one hole in a car fender and on the second hole snapped off several teeth and was a paperweight. Had some nice teeth the cut well but once one snapped off it was unusable.

It's pretty well made for a $15 import. I've cut 5 holes through 1/8 plate steel with no issues, except for the kick out spring on the pilot likes to slip down, but hey, it's sharp and precise.
