Mollom (1-15/16''|49mm) Heavy Duty Carbide Hole Saw with 2 Pilot Drill Bits, Hole Cutter cuts Stainless Steel, mild Steel, Iron, Copper, Brass, Plastic

I was wary of the pricing, but this is a really good hole saw. I had to cut a precision hole in an aluminum marine dashboard & this worked perfectly and the edges were smooth and clean. The tool cuts fast. It's sharp, and it works well.

Be aware that the bit will 'grab' more - especially with metal vs: wood - than the same size, regular Bi-metal bit with more numerous teeth.

Why did you pick this product vs others?:Yes, it works on plastic. But still start the drill as slowly as you possibly can.

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!

Please save your valuable time and read latest reviews. This is the second order I place with different supplier (see both photos). He common factor: both Chinese madre.The first one, the springs did not fit, this order, the springs are missing compared to the specific photos. The saw itself is defective in quality. See photos, including he advertised vs. what I got. Second return.

Cut through 3/8" hard stainless, took it slow, used coolant lubricant.

I used it in plastic to make holes for a front bumper cover and it worked perfectly

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
