Hole Saw 3 3/4” (95mm) for Wood and Plastic, HSS Bi-Metal Hole Cutter Core Drill Bit for Drywall, PVC Boards, Fiberglass and Vent Pipes

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.

not sure about longevity but it cut just fine. used it once so far to drill hole for ac unit hoses

This is a great priced hole saw. Thick steel body won’t warp. OK, if I was drilling holes for a living, I’d choose a carbide tipped version, but I’m not, and it did a nice job cutting on pine and plywood soffits. Very pleased.

Does good job working with 1/4in mild steel. However, it has excessive wobble in the drill press. I would still purchase over again because it does cut well and holds up well in mild steel.

The media could not be loaded. I received this hole saw today and I can't help but say I'm impressed for the price. It wasn't the cheapest of the three recommended saws. But I was looking for functional and not cheap. The price difference was perhaps $5. But this thing is built like a tank. The workmanship seems to be extremely good and the welding, fit and finish are excellent. The base plate looks to be approximately 1/8 in thick and uses a standard two post arbor. Some of the other hole saws mentioned using a non-standard arbor. The only nitpicky downside I can find is it when the arbor is fully engaged it wobbles a little bit. But it runs solid and true even at high speed.

I got this hole saw to cut holes for shower fixture plumbing. It worked really well for my uses and wasn't expensive.

I bought the 3-1/8" size to cut holes in a few hollow doors (veneer). Initially, the product worked very well, cutting the holes efficiently and clean. After about the 4th hole, the teeth were not cutting, and I could just smell burning wood and some smoke. I was able to manage to cut 2 more holes, but that's about all this can handle. If you're only cutting a few holes in soft material, you'll probably be fine. If you're looking for something more durable, you'll probably want to check out some other products.PROS• Cost• Easy to install and useCONS• Not durable (lasts 4-6 cuts)

Actually better quality than expected. Heavy duty. My only complaint is the pilot bit is a little short. However it is worth the money and works great for cutting a perfect size hole for an 8 inch speaker.
