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.

Very easy to drill

It cuts hole fine, but the way the blade secures to shaft is dangerous. When I did a test spin before using, the blade spun off and cut my hand when the drill stopped. Doesnt have a nut to secured the attachment like higher quality hole cutters do. Use with extreme caution and no one else around is advised.

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.

Great tool to put holes in for recess lighting.

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

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.

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.

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!

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.
