Hole Saw 3 3/8” (86mm) for Wood and Plastic, HSS Bi-Metal Hole Cutter Core Drill Bit for Drywall, PVC Boards, Fiberglass and Vent Pipes

Excellent product for the money, works well and durable

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.

I bought this ITOOLFIRM hole saw to cut through drywall for old-work ceiling pan electrical boxes. I only had a couple to install, so I went with this less expensive one and was really impressed. It cut very clean holes, surprisingly fast, with zero kickback. The drywall plugs even released with just a few taps. If you need to cut a 3-5/8” hole, this is the perfect saw.

Purchased to cut holes in sheet rock for mounting 8” recessed lights. Works well but of course with such a large hole saw you must keep tight control. Cuts as it should. Easier than cutting with a razor knife and makes a very clean hole.

Arrived on time. Works as described & good quality!

Worked great for me. Still very sharp bought tonight lights into my aluminum bumper in the rear on my truck

Works exactly as expected, makes perfect holes for light fixtures.

Fast and worked as it should in the 5 3/4 size but the 2 7/8 did not want to cut good at all.

I used this for cutting 3” holes in wood to install soffit vents. The hole saw had a fast cut and worked very well for me. The arbour also fits hole saw bits I currently own, which was a bonus.

Fait très bien la job! Il est solide et a bien coupé le bois.

Excellent product good saw

The price is excellent, and the drill insert is sturdy. I use it with much larger hole saws without any issues.

Good product
