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

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.

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 got it to cut 120mm holes in computer cases. So far its fine exactly that. If it cuts about 6 more, Ill say its paid for itself and Ill be happy. Curious to see if my other saws will fit the auger.

The diameter is in mm not inches. It is close to 2 7/8, but not exact.

I own many whole saws but I needed one 10 in diameter. This hole saw assembly is not like any other that I have ever owned. Product kept coming apart while in use. No directions with this product at all. No paper work what so ever. I consider this a waste of my time and money.

Using it to cut holes for hydroponics rails. Makes hole just big enough for trade gallon pots to fit in. Only cutting about 1/8” through the top of rails but does the job and it includes an extra arbor that fits my Lennox hole saws too.

Good product for a good price

We used this to drill holes in a wooden beam to install lighting. It worked very well

Bought this to put in soffit vents. It works great!

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.
