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

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.

Liked how nice it cut

Granted it was just aluminum, but I had to cut through some half inch stock. This thing cut like it was butter. No Chatter, grinding, wobbling, binding, smoking, burring, or chipping. I was impressed.

The pilot screw breaks easily. Was just trying to go into 4 PVC Schedule 40 and the bit breaks like nothing. Seems to be a good product, but the pilot drill bit is very flimsy. This is paperweight now until I can buy another pilot screw. Not strong at all.

Does as its advertised. No regrets buying it. Cuts through 1/4 inch aluminum like its nothing.

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

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

Nice product at a reasonable price

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

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.
