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

Broke the first pilot bit and order 5 more… didn’t break a second.. It did the job of cutting into my well casing…seems to be undamaged. It not a very easy hole to drill drilling into a non flat surface do yourself a favor and start on your lowest clutch setting or you will break the pilot.. It did have alittle wobble to it. But not to bad.

Best hole saw that I’ve used to date.

Drilling through the sheetmetal floor of my van tore the teeth right off this hole saw. Toothless, it failed to finish the first job I gave it, and then I toss it in the trash. Money wasted.

Cut the size I needed and hardly looks used.

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.

Drilling one hole at 100 rpm in 1/4 304 stainless. Drill shaft broke before hole was finished.

Keep the tines lubricated while cutting .

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.

I hv many holesaws. This was extremely well made. Cut through steel like soft butter. Very impressed.

Teeth stay sharp, bell doesn’t flex, this works great with a drill press.
