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 has a unique arbor which is very light duty. You cannot use arbors you already have which are more robust.

Hole saw itself is ok but set screw that holds drill bit is too small and threads are terrible. Does not have a retainer or set screw to lock the holesaw blade so it unscrews itself constantly.

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

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.

good product

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.

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

This is a great bit for the price. I have the 6 1/4 and a 4 1/4 both were used on putting lights in my ceiling works way better than the carbide bit you get at Lowe’s it creates less dust, but make sure you use a dust bowl and it’s virtually dustless. Just have to go a little slow when starting but after that you can go full blast and it doesn’t catch well for me it did it anyways.

Great tool to put holes in for recess lighting.

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.
