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

Great tool for drilling hole in shipping containers to install vents. Go slow at a angle, with coolant, cause that corton steel is hard. This hole saw stands up to the test.

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

Smooth cit in 1/4 steel four holes and works great

Not bad. I cut our kitchen sink that has 18 gate metal. It cut fairly easy. Would recommend

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

I only had 1 hole to cut, but it did it fast, clean and easy.

I was skeptical about these by how cheap they are, but it works great. I even decided to buy the 5 pack afterwards.

You get what you pay for with this. It has carbide teeth but expect several to break off if you have more than one hole to drill. 4 holes in 1/4 mild steel and itll be past time for a new one.

Le facilita hacer el trabajo

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.
