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

Worked great for cutting perlins to fit around 2 3/8” pipe

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.

I used this for some mild steel (1/8 ~ 11 gauge) and it worked great. Jumps a little bit, but I was drilling upside-down. Definitely better that then Milwaukee Hole Dozer from Depot. Cuts big chips, they are HOT. Wear long sleeves and protective gear!

For the price I thought this was a throw away but it was quite nice. Have not subjected it to repeated use but surprisingly good.

Bought 2 different sizes and extra bit pack. Complete waste of time and $$. I am experienced tool and craftsman, this is worst cutting product i have seen all my life. The center drill bit is so brittle it breaks immediately with little to no cutting pressure at all. Bad, Bad Bad!!!

Cut 4 holes in the floor of a work van, still sharp as new.. Great product

worked well on plastic hobby box - clean cut, no shattering around hole

Inner and outer parts of the drill bits are not concentric to each other.

Best hole saw that I’ve used to date.
