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

Got the job done

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

I’m in construction and have to drill holes in metal studs often. Regular hole saws get hot and don’t stay sharp for very long. This saw is just the opposite last forever, and is twice as fast. It’s a beast.

Cut fine but a weak shank that breaks almost immediately when you start to drill. Might be ok in plastic with a very weak drill motor.

So typically, a hole saw is a couple mm’s over what it’s supposed to be due to poor teeth alignment. However, this hole saw is PERFECTLY 48mm. go figure… 6 stars

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

Was missing set screw and I can only return it. :( Better QA before packaging would have been nice.

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

Excellent piece of equipment. Cut right through 1/8 metal. Would buy again.

I used this to drill a hole in my bumper for a block heater. I thought it would take two due to quality, so I bought two of these. Turns out it is of great quality. I will use this for years
