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

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.

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.

Great price. Worked well for cutting in lights. Only complaint was had to really tighten to keep it from spinning off the spindle when my drill would stop. Little Teflon tape fixed it up

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!

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.

good product

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.

Could have more teeth to make it not catch so hard when you start.

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.

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