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.

This hole saw worked perfectly. I needed one to cut 2 holes for recessed lights on my back porch. At the big box stores these blades from Lennox and other brands are around $45-$50 for 1 in the size I needed which was way to much for the one small job I was using it for, especially since the lights only cost me $15 each. So Amazon to the rescue! Ordered this and had it next day and the job is now complete. If you’re a pro using this every day maybe the name brand is worth the extra money, but this was only needed for 1 specific job and it worked great. Highly recommend.

Great price. Worked well for cutting in lights. Only complaint was had to really tighten to keep it from spinning off the spindle when my drill would stop. Little Teflon tape fixed it up

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.

good product

I did 26 holes without any problem. Still not slow down. Really cheap and work like other big brand name in the market. 10 stars for this saw

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.

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

Havent tried on metal. Works well. The arbor is holding up, so far.

I needed exactly 4” in a hole saw. As it turns out, 100mm is labelled only 3 15/16”. That being said, it makes perfect 4 holes which have worked for all my 4 mounting applications.
