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

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 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

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

Nice product at a reasonable price

EDIT: After using a better drill bit and Blue Loctite on set screw,, the hole saw worked fine. Bumped it up to 3 stars and overall, disappointed but made it work. Drill bit did not center properly and even broke on a test piece. Will update after I use a different bit and am able to complete an actual cut. This is currently being used on aluminum, 1/2 thick.

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

Product was as advertised

Excelente producto y servicio.

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.

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