Cuts drywall without damaging wall finish Proper size for electrical box

Looked like it would work good but havent used it yet got it to move my dryer vent

Exceeded my expectations despite the very inexpensive cost! After drilling 15 holes through plaster and plaster board, the blade is still sharp. I just needed it to last long enough for this one project, but looks like I can keep it in the toolbox for future.

NOT WORKING ON SSTEEL AS DESCRIBED

So why ask me to write a review if you won’t post it. Just telling you like it is. So if it is neg. You won’t use it . I’am glad that works for you , will think twice before I order again.

Cant use it at all. It was shipped with the wrong arbor. The thread on the arbor is way to small for the saw. Dont waste your money.

This is a decent, cheap hole saw that gets the job done. I used it to cut holes in ceiling drywall to install remodel 6” recessed can lights. Unfortunately, this saw measures slightly under 6”, so the resulting holes were not large enough to fit the cans. I had to enlarge them a bit with a drywall saw, which then defeated the purpose of using a hole saw to make clean cuts and minimize dust in the first place. Also doesn’t last very long… it was adequate for what I needed without breaking the bank, but you get what you pay for.

This came with the threaded hole way off and stripped out before the first hole was complete.

not so great for stainless steel

The hole saw is not exactly the 4 inches I needed to put in a exhaust duct on my roof I was able to use the same holesaw and Waller out the hole. For the value it’s not bad you’re just not gonna have a perfectly outside diameter 4 inch hole you’re going to have to work for it. It’s a Chinese tool... I mean lol
