(3-1/2''|89mm) Heavy Duty Carbide Hole Saw with 2 Pilot Drill Bits, Hole Cutter cuts Stainless Steel, mild Steel, Iron, Copper, Brass, Plastic

I bought this to drill a hole in 20 gauge stainless steel. It cut great. This may not be the longest lasting bit, but pro bits for this type of cutting are over 4 times the price. I needed to make one hole, and it did it surprisingly well and fast. Since others noted that the pilot bit can snap, I drilled the pilot hole with a separate bit. That took awhile. But when I switched to using this for the large hole, it cut fast. Make sure to use cutting oil, and go slow. I could easily see the shards and honestly it felt like I was cutting aluminum.

I've had to use this bit several times. It has provided great service and stays sharp. Excellent purchase.

I used it to drill 17 holes in 1/8" aluminum plate and it worked a treat. The pilot drill was starting to squeak a bit towards the end, but the hole cutter never skipped a beat.

Cuts a good hole, however the Allan wrench that was supplied with it is to small

Cutting @ slow speed with steady pressure and plenty of cutting oil, this hole saw cut through my 1/8" thick mild steel bumper with zero problems. Stayed very sharp through the entire process. The pilot bits fit perfect and the saw followed the center hole flawlessly.

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

I ordered several sizes of carbide hole saw from the Mollom brand, and I've been pleased with all of them. They run very concentric, and don't have nearly as much run out as the typical screw/pin arbor hole saws. When used in a drill press with a drop of cutting oil between holes, they seem to last forever. I've done 100+ holes in 1/2" mild steel plate without any issues.The carbide teeth on these hole saws have a slight chamfer on the interior corner, which locates onto conical/spherical features very well. I've been using this feature to step through hole saw sizes for making bearing seats and counter bores by easily locating off of the partial cut made by the previous hole saw.

Update - 6/15/24The seller reached out to me after my review and apologized for the quality of the product. He acknowledged they had some quality issues and were addressing them. He offered me a 100% refund of my purchase. For this level of professionalism and customer service I am raising my rating from 1 to 3. The seller did not request me to update my review or put any stipulations on my refund.I should have known. Get what you pay for, in this case not even then. I bought to drill holes in 55 gallon metal drums. Thin sheet metal! First hole took forever to drill. Second hole the center bit broke and three carbide teeth broke off the hole saw. What a waste of money.
