I bought it for through hole making on the heavy duty machinery. It only takes a few seconds to drill through a 1/8'' thick aluminum sheet plate, which is much efficient compare with step bits. I love it.

We install fire suppression systems in commercial kitchen hoods and have to drill several holes in stainless steel. This hole saw kit from GreenLee Last for several installs before needing to be replaced. The quick connect feature works flawlessly changing out different size holesaws in seconds. I would highly recommend this kit. It is pricy but it pays for itself in longevity and easy of use.

Great set. A little cutting oil and these bits will last forever. Love the quick change set up. Definitely worth the money. Just keep in mind they are not trade size. So the holes only go up to 1 1/2” conduit. Still definitely worth the money.

I got this to cut a series of 2" holes through 1/8" tough steel plate, using a handheld power drill in an awkward location. It took a while to cut (using plenty of cutting oil and going slowly) but made consistent, clean holes time after time. The bits still look great after 15 or so holes. The pilot drill cuts quickly (although I found it was even faster if I first drilled a 1/8" guide hole). The rim that keeps the bit from punching all the way through the hole is *genius* - makes it way easier to finish the cut, because you don't have to worry about the bit plunging through and damaging whatever's behind your hole. My only complaint is that the spring that ejects the blank is pretty strong, and you're pushing against it the whole time in order to hold the bit against the cut, which is extra work.

So you're looking at these thinking if it's worth the money. Well it depends. I've used multiple different sets over the years. This set is very nice and works beautiful. The Ideal set I had, it was nice and worked beautiful. So what makes this better? I find the overall price. With this set you can replace each individual piece. Making for a cheaper replacement. As with the Ideal set you have to buy the whole piece making it cost more. So if you're manly having a carbide cutter for occasional use I'd lean towards a cheap set but a full time commercial/industrial electrician I'd say get it.The bigger sizes of the carbide hole saws or any hole saw really, seem to go slow and be very hard on the drill. I'd say after 2" go for the slug buster.

I have been struggling with cutting holes in stainless steel sheet metal and kegs until I purchased this set, works better than I could imagie. Have only used in a drill press but have cut around 20 holes with the 2" cutter and it continues to preform well. I use slowest speed, some marvel mystery oil for cutting lube and lots of down pressure, Sometines the cutter will catch near the end of the cut. I assume my technique needs improvement. It's an awesome hole saw set. The pro - the hole saw is a shallow cutter, great for electrical enclosures, the con - the hole saw is a shallow cutter, not perfect for cutting into the sidewall of pipe or pipe notching.
