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 was able to cut about 50 holes from 3/4 plywood for a prop project. The center bit broke once (it came with one replacement) and the tool was still sharp enough at the end to finish the job.

good product

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

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

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.

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.

Be aware that once the hole saw is used, it becomes nearly impossible to remove the center drill bit as it becomes very tight. Perhaps some WD-40 oil will work to get it free. The hole saw does come with 2 extra center drill bits and an Allen wrench.

It works great.

I used this to cut 15 recessed light holes and still has life left. I did use it on plaster and it cut through about half way. So good for drywall not good for plaster. I would buy this again
