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

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

Best hole saw that I’ve used to date.

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!

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.

So far I have only used the 2 1/8” to cut through 1/8” thick aluminum. It cut well. My only grimace is that one saw was glued tight to the foam below. The paper chart inside was damaged by the saws, my suggestion is that they could make it no blemish by giving a metal chart instead.

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.

I bought the 1 7/8 inch carbide hole saw. I needed to drill through a 3/16 steel bumper on the back of the jeep. No problem at all. It worked great. I did use oil as it cut through the steel.

Keep the tines lubricated while cutting .

I was originally happy that I found a cheaper hole saw compared to the EZARC brand I bought previously but the picture showed the result after the first use. All the carbide cutting tips that are welded onto the tool broke off from their welding. I was trying to cut through about a 1/8 sheet metal. Sheet metal 1, Mollom Hole Saw 0
