Hole Saw 5 1/2” (140mm) for Wood, HSS Bi-Metal Hole Cutter with Pilot Drill Bit for Plywood, Cornhole, Ceiling and Drywall

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.

Excellent product for the money, works well and durable

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.

works great. if you need to get the piece lodged inside after cutting use two wrenches to open the saw. do not put presure straight easy does it

It cuts very well but the size for a 5 inch hose with a larger flange to fill the hole that connects to the hole wont fit. So you need to make a 5.3/4 inch hole to fit the 5 and a half inch flange that the 5 inch hose screws into, and fits into the hole. The hold needs to be bigger than 5 inches to accommodate the vent flange that fits in to hold the 5 inch hose.

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

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.

Muy buena herramienta

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.

Great hole saw, used on wood and worked out great!

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.
