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

For the price it worked well, compared to Milwaukee that I purchased for $65.00, there is no locking mechanism on the Milwaukee (nut) to secure the blade on and it spun rite off very dangerous. This hole saw worked well at half the price cut like butter threw plaster. I used it to punch out six wholes for recessed lighting!

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.

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.

it went thru 1/4 aluminum plate but very slowly. but it did work. probably better in wood or softer materials.

Reverse the drill when using this to cut ceiling tiles and it works great. Also does nice on wood. But a caution note. The drill bits seem a little fragile. I dropped one while in the blade and it shattered.

FIXED, NO BIG DEAL! THE O-RING CAME OFF EASILY. The first thing that I noticed was that the cutting blades were assembled wrong.

Very sturdy and sharp teeth. Very well constructed
