As the photos show, it did a perfect job cutting a 6 1/2" hole in my new cielling of 1" thick tongue & groove pine boards for new low-profile/flat LED recessed light fixtures. I cannot say anything meaningful about longevity of the hole saw, like many here in the reviews, I just have this small project of the cielling with 5 lights to do. After that, it's going to get put away for future need thar may never come. Or get lent out to a relative someday. However, 1" thick pine is a tougher challenge than the drywall the majority of people will likely use it on, and it did the job well. And checking around, the least expensive alternative in a local retail big-box home improvement store was $7 more. And it was the flat carbide "bumps" type that's better on drywall or tile, and difficult to use on wood. And it's no different as it is made in China too. My only significant advice is that big & wide hole saws, no matter the brand, put a huge amount of torque on the drill. And if they catch, stick, or kick in what you're cutting, they can twist the drill very SUDDENLY and very HARD. This can knock you off a ladder. Or posibly twist the drill so the battery box slugs you right in the jaw, as hard as a decent boxer's punch. If you haven't used one before, it's really worth 10 minutes of time to practice on a piece of scrap board similar to what you plan on cutting the hole into. It's important to get a feel for how the saw behaves on the drill's "Fast - Drill" and "Slow Hi-Torque" settings behave. Plus, it's good to have an understanding of how important it is to keep the saw level and square to the surface you're cutting. Because angling it unintentionally is what will make the teeth on one side dig in, stop the drill, rip it out of your hand, and make it slug you in the face. And, if your drill has a side handle for an extra 90° hold, use it.

This worked for my use case, and saved me a lot of money instead of buying a name brand one for 50 dollars after you add in the cost of an arbor. I cut 10 wood holes for cup holders on a poker table.

Used to install soffitt pot lights. Worked great. Remember to start in reverse to cut a groove and then switch to forward. Much better price than box store. Even if it doesn't last it cut *8 holes for me nice and clean.
