Mollom (1/2''|13mm) Heavy Duty Carbide Hole Saw with 2 Pilot Drill Bits, Hole Cutter cuts Stainless Steel, mild Steel, Iron, Copper, Brass, Plastic

Very surprised the 2 1/4 hole saw I order was able to cut 1/2 316 stainless steel plate. Definitely can cut more than one hole with it. That being said the hole was a little rough. Overall good tool and will be purchasing more.

Nice quality. Makes a clean, precise cut. If you are using a drill press, you might need to adjust the belts to change the speed as it doesn't seem to like it when you try drilling at too fast of a speed.

I bought this bit to drill through sheet metal and galvanized metal posts. I was kind of skeptical at first because it didn't look like it was going to do the job. It started out unimpressive because it didn't seem to be cutting through the metal at all, but then it powered through and got the job done. I believe there was a film or a coating on the bit that impeded its initial ability to grab and cut. After cutting several holes this bit is still sharp and ready to keep going.

Good Product. I would give 5 stars but I had one issue that reduced the rating. The pilot bit hole was not drilled deep enough, so one of the pilot bits would not seat enough to allow the allen set screw to engage. Aside from this issue, hole saw is REALLY good!! It ate through my stainless steel sink deck super fast. Would buy again.

It work very well for the job needed cut thru with ease!!!

When it came in, it’s nicely packaged has a nice little carrying box and assembles pretty easily, but the one problem is that the drillbit sucks. It snaps right away, but the hole saw itself is actually really good. All I had to do was take one of my Mac tools drillbits. and put it in the hole saw and try to tighten it down without stretching the threads on the lock screw and continue the cut, but the only problem with that is because it doesn’t have the flat spot on the drillbit like the hole saw but had you have to keep tightening it down but on the plus side you can get at least 2 to 3 full cuts with using a Snap on or Mac tools or high-quality drillbit and guess what if it breaks lifetime warranty on Mac tools drillbits, so breaking one isn’t that big of a problem I am giving this tool a three star because the drillbit snapped right away but the saw portion is actually decent quality. I don’t know how long it will actually last but drilling through a bumper. It worked really well if it was just the saw I would give this a five star and it’s packaged decently, so if you’re looking for a cheap decent hole saw this would definitely be one of my first picks but if you’re looking for something more long-term, I would definitely look into a better company with higher quality tools, but for a couple time use and possibly maybe only being used once a year or a couple times a year then this is definitely the product for you, but if you’re using it daily weekly or monthly definitely buy from someone else and I would recommend tools because of the warranty Snap on doesn’t really have the warranty backing their drillbits or heavily worn tools Mac tools is just a better option all around and if you don’t have a MacTools dealer and I would recommend googling for better options for you and what you do for a living or hobby’s Buy for side projects this isn’t that bad

Love these hole saws. Great price.

I drilled a hole through metal 1/8 inch thick metal. It worked well, make sure you keep it vertical to the hole when cutting, don't lean. Also, the center bit falls out intermittently while drilling and you have to reinsert it, just be mindful!
