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 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 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.

Hole saw itself is ok but set screw that holds drill bit is too small and threads are terrible. Does not have a retainer or set screw to lock the holesaw blade so it unscrews itself constantly.

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.

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

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

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

Very easy to drill

If all you need is one hole and do not care that the saw wobbles excessively - namely you dont care what it looks like or how precise a hole you need, this could work a few times on soft wood. If you need a smooth hole cut in good wood in an exact location or want to use it multiple times (not hidden behind a wall for example) pay for something better. Not returning because I had to use it to find this out. Luckily I did a practice hole and avoided trashing the cabinet for which II purchased a 70mm hole saw. Now I need to buy a better quality hole saw to do the job and keep this junk, too. If only there was -1 stars for accuracy and value. Two stars if you need something cheap for a hidden hole.
