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

Liked how nice it cut

spring applies pressure on wood before blowing out and splintering the backside of the cutout. wood dust also clogs the cutting teeth.

Granted it was just aluminum, but I had to cut through some half inch stock. This thing cut like it was butter. No Chatter, grinding, wobbling, binding, smoking, burring, or chipping. I was impressed.

Was checking on the comments and trying to buy one. Although not as good as Klein, looks all things go fine, better than the cost. Worth it.

Bought the 180mm (7.x) hole saw to drill a hole in a 250 gal propane tank, my smoker project. It cut it, still has its teeth and I presume would be able to cut more. I figured it was a 1 and done use but if I ever need to use it again it might have some life left in it. Worked out perfectly for the 7 pipe Im using for the stack.

Best hole saw that I’ve used to date.

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

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

We were putting a dead bolt in a metal clad door. Bought a supposed metal drill bit at a local hardware store, lots of sports and it put a dent in the door. This bit went through the door in no time, absolutely no problem.

Used to install light on my trailer. Cut 12 holes and it the saw is still like new.
