My analysis of this hole saw showed that it is not worth the investment. The blade dulled quickly and struggled to cut through even modest thicknesses of material. The only pro I can think of is that it looks nice, but that's just cosmetic. The cons far outweigh any benefits - save yourself the frustration and stay away from this tool.
Pros
Efficiently cuts through stainless steel with ease
Cons
May struggle with thicker materials or tough angles
I use these daily and they work well. I recommend using some line oil to prolong their life, just like any other drilling product. Cuts a true 3/4" hole
Pros
Package dimensions: 9.144L x .508H x 14.478W (centimeters)
I have a set of these quick change saws and they are amazing. Chew dropped the stainless steel and easily bit into other metals, creating nice clean holes. The best part is that it's a quick change, I don't have to disconnect and re-solder every time I change saw size.
