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 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.

Clearly not the most expensive which reflects in the workmanship. I am using this for cutting into vinyl siding which it is going to do satisfactorily. If you need one for a more intensive job please consider a better quality

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.

Cumple todos los requisitos, con calidad

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!

Great tool to put holes in for recess lighting.

Product arrived with all items needed. Was easy to use. Quality seems above average and cant beat the price.

Do the job.

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

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.
