Seimneire 6-1/4 Inch Hole Saw with Heavy Duty Arbor, 1.2 Inch Cutting Depth HSS Bi-Metal Hole Drilling Cutter for Smoothly Cutting in Wood Cornhole Boards Plastic Drywall & Thin Metal

Muy buena la recomiendo

I needed this to cut a rather large hole. At the time I was not aware that the exact size I needed was available. Now I have both. This tool is capable of cutting variable size holes. Unfortunately the holes are not that clean of a cut. Which means that once you cut the hole, you will need to spend time cleaning up the edges. I finished the hole using a dremel bit. Also, I had to shorten the tool arm to fit it in my drill press. I was cutting a hole in 1/4 thick plastic. That required that the material be secured and that the cutting tool not wander. I think maybe this tool is more for some other material...drywall? As it is I finished the project and it looked acceptable.

The hole saw itself is a fine product. Its sharp, cuts cleanly when using the painters tape trick. Seems manage dust fine as it didnt leave any burn marks. I dont expect to use this blade often but I expect it to be good enough to be the last 3-1/8 hole saw I buy. However the arbor doesnt run true. There is definitely some run out that cannot be attributed to the drill. Be warned if you use the included arbor as it may lead to inaccuracy. But fortunately the hold saw has the standard threads so you can just use any other arbor and it works a treat. 4/5, ironically it would have been 5/5 if they didnt include the arbor.

Very sturdy and sharp teeth. Very well constructed

Worked well for me. I used it on ABS plastic so i do not know how long it would last on metal, but it worked great for what i used it for.

Good value. I needed it to complete a one-time Kitchen exhaust installation.

Makes installing wafer lights a breeze.

The locking chuck was a little loose but it worked quite well. I mean it’s a hole saw. Not brain surgery. Lol

Very strong and grippy and drills great depending on your drill

It does the job but I see why they sent 3 drill bits with it. The first one broke on the first use. But I was able to finish the job without any others breaking.
