Luomorgo 4.5 inch Hole Saw, 1 1/4 inch Cutting Depth HSS Bi-Metal Hole Cutter for Wood Cornhole Boards Plastic Drywall & Metal Sheet

It works great.

I was able to cut about 50 holes from 3/4 plywood for a prop project. The center bit broke once (it came with one replacement) and the tool was still sharp enough at the end to finish the job.

Be aware that once the hole saw is used, it becomes nearly impossible to remove the center drill bit as it becomes very tight. Perhaps some WD-40 oil will work to get it free. The hole saw does come with 2 extra center drill bits and an Allen wrench.

I bought this to drill a hole in my fender to install a snorkel. Did not want to spend a ton on a name brand for just one hole. This did the job and I would buy again.

My house is old. I have installed LED lights in most of the rooms at this point, and these hole saws never seem to last too long. This one worked fine for its purpose, and was cheaper than the one I bought before from Home Depot. So that helps. For context, all of the ceilings in my home are double layered drywall, with a layer of wire mesh in between, which is beyond annoying. The teeth on these saws always get worn down fairly quickly because of this. Im sure that eventually I will have to replace this one as well. The last project I did was in my living room, which required 10 lights. I used this saw for about 6 of the 10 holes needed. The teeth on this one still seem good so far.

Could have more teeth to make it not catch so hard when you start.

I ordered this in 120MM and a JIECHENG 4. This one is much heavier and not just due to diameter, It also comes with 2 arbors, my preferred with the side pins and the simple thread in and a total of 3 bits. The JIECHENG only has the simple thread in and no extra bits. I usually run Milwaukees but didnt feel like heading to the store for a 4 and a 120mm just wasnt going to get stocked here. I cant tell you how either will stand the test of time as Im going to just add some vents/ducts through plastic and thin wood a few times and then let these collect dust for the rest of time. Still weight + extras + being 1$ cheaper makes this a winner for someone who only needs to make a few holes. Sorry that I will not be using it more so I cant give you a better idea about long term value. I dont think anyone runs a 120mm on a small drill so I do not think the extra weight will be a problem.

I recevied it yesterdya to drill 4 1/4 holes for my recessed lights. But when I screw the drill bit in the center and attach it to my drill, when I turn the drill on the cutting circle inscrews from the drill bit. UNless my kit is missing something....shouldnt there be a nut that screws on the inside of the cutting circle to keep it from spinning off? I mean I think I am a little handy, but I feel like an idiot.

Used this for drilling holes to retrofit LED ceiling lights under an exterior porch in plywood. Perfect fit for the lights and durable tool. The 3 heavy duty drill attachment options make it versatile for most any type situation.

I used it to drill multiple holes for a 32 roon purple martin house and some gourds. It worked well and still is sharp and ready to go.
