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

Do the job.

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

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!

It works great.

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.

Product arrived with all items needed. Was easy to use. Quality seems above average and cant beat the price.

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.

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

Good product for a good price
