These bits last a very long time and fit through stainless steel and chrome pipe with ease, just remember to cool them! For stainless steel I use plain old water with a spray bottle. Just remember to keep it cool and use the right pressure, they last a long time and the price can't go wrong It's M42 cobalt steel construction.
Pros
1 1/2" depth of cut and sharpened teeth for long life
I had to cut four holes in the metal casing of the electrics and it worked. It only took four cuts and I used lots of cutting fluid and a drill press. It was humbling to use but I think I could cut a few more holes if needed. The metal box was YuCo Yc-20x20x8 IP65, 16 gauge, inside/outside wall standard case, 20" H x 20" W x 8" D.
Pros
Large holes in the base allow for quick removal of the cut material
I may update once it works but for now it's a lot It's annoying that I ordered a blu-mol hole saw, but it doesn't fit the wedge mandrel from my blu-mol set of 6. If they change the style it would be nice to have a warning that it might not match the old sets or something like that. Because why else would I bother to buy the same brand?
Pros
Wide slots on the side panels and bottom plate for better visibility when cutting
