Mollom Heavy Duty Carbide Hole Saw, Hole Cutter cuts Stainless Steel, mild Steel, Iron, Copper, Brass, Plastic (3 76mm)

Very good drill bit, cut fast and did a great job

Very happy with this hole saw, super sharp. Leaves a nice clean hole in aluminum and plastic.

I read most of the reviews on this 2-1-2” hole saw and tried it anyways but bought two just in case. The first one went through no problem I was drilling through 1/2” steel plate kept the lube to it was patient and no issues. The only thing was the spring to push out the piece came off pretty much right away. Didn’t chip any teeth and worked fine. And some reviews said over sized but as you can see it wasn’t.

Worked perfect on 1/4” S/S plate. Fabricated a base plate for a swimming pool ladder.

Bought two, and both drill oversized. One drills 0.20 oversized and the second drills 0.30 oversized. If you are drilling say a bolt hole, it’s a really sloppy fit. The quality of build was fine, but the accuracy wasn’t.

Material resistente

Got the job done 8 holes in 3/8 steel plate

Got the job done

So far I have only used the 2 1/8” to cut through 1/8” thick aluminum. It cut well. My only grimace is that one saw was glued tight to the foam below. The paper chart inside was damaged by the saws, my suggestion is that they could make it no blemish by giving a metal chart instead.

Awsome holesaw need a very powerful drill and a strong grip and lots of oil
