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

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.

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

Heavy duty tool that is way more than a DIY project needs. Cost was great for the tool. It puts other hole cutters to shame.

Came in short wait time was excellent for cutting 16guage metal cut clean was very useful thank you

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.

there nice and sharp not a step drill bits but cut i figure about a year for replkacement do good cheap set to have

These hole saws are amazing. Quickly makes holes in thicker steel.

Well it drilled 2 holes fine, then broke. This was the 3 1/8 flavor, chucked up in a drill press, so I couldnt have bound it up too much the belts will slip. You get what you pay for.

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

Use a god oil to lube hole cutter when using it.
