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

It works great.

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.

We used this to drill holes in a wooden beam to install lighting. It worked very well

I did 26 holes without any problem. Still not slow down. Really cheap and work like other big brand name in the market. 10 stars for this saw

The hole saw is very high quality. I was expecting something with lighter gauge metal. I used this tool to cut holes in a drywall ceiling to install LED lights. Each hole took less than 10 seconds to cut a perfect round hole. I saved lots of time and headache. I made sure that I bought a hole saw with the spring around the drill bit in the center. It keeps the drywall disk from getting stuck in the hole saw. It makes all the difference. I price this item at Loews and Home Depot and it was $34 and $42. If you price it out, youll see the same thing.

Very easy to drill

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.

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

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.
