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

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.

Bought this item to make the holes to install the recessed lighting in my kitchen. Worked fine once I got it on right.

I bought the 155mm/6.1 in size to cut the exact hole needed for the Ensenior 6 Pack 6 Inch Ultra-Thin LED Recessed Ceiling Lights (which I really like). This hole saw makes the job much easier. As noted by others, if not careful, this saw can catch and give some nasty kickback. Also, the 2nd arbor that comes with the larger sizes is really nice in its design using a secondary ring to move 2 pins into the bottom of the hole saw; if only the pins matched the holes in the saw so that it could be used, this would definitely be a 5-star item. As it is, Im hoping the arbor will fit something else that I have.

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

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.

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

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

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.

Great tool to put holes in for recess lighting.
