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

Havent tried on metal. Works well. The arbor is holding up, so far.

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.

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

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.

I needed exactly 4” in a hole saw. As it turns out, 100mm is labelled only 3 15/16”. That being said, it makes perfect 4 holes which have worked for all my 4 mounting applications.

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.

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.

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.

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.

Advertised as 3 but is only 2-15/16. May not sound like a big deal, but if the hole must be 3, then this falsely advertised item will not do the job!
