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 like how this comes with the pilot drills and it was all super easy to assemble! You cant beat the quality either. The teeth are sharp the paint is bright and smooth without getting stuck on the wood or plastic Im cutting and just an all around good buy. This cut through with out a hiccup and I couldnt be more pleased. 5 stars!

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

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!

This hole saw worked perfectly. I needed one to cut 2 holes for recessed lights on my back porch. At the big box stores these blades from Lennox and other brands are around $45-$50 for 1 in the size I needed which was way to much for the one small job I was using it for, especially since the lights only cost me $15 each. So Amazon to the rescue! Ordered this and had it next day and the job is now complete. If you’re a pro using this every day maybe the name brand is worth the extra money, but this was only needed for 1 specific job and it worked great. Highly recommend.

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.

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.

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

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.

Do the job.

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.
