The last one I bought was a 1" hole saw for tile It cost $15 in Home Depot.
Depending where you rent it, between 30 -45 per day.
Yes, you would have to use 2 different types of hole saws. 1. Diamond Sintered hole saw to get through the porcelain to stop it from chipping. 2. Aluminium hole saw to get through the cast iron. Goodluck!
You should be using either 1. Bimetal holesaw 2. Diamond holesaw or 3. Tungsten Grit hole saw Goodluck!
A 40mm hole saw is more efficient than a drill bit for holes of this size.
If you mean a 'hole saw' -which cuts a circular hole, - then there are versions of them to cut wood, more expensive ones to cut metals, and really expensive diamond tipped ones to cut tile and stone.

To enlarge a hole using a hole saw, you can start by selecting a hole saw with a larger diameter than the existing hole. Then, carefully position the hole saw over the hole and secure it in place. Next, slowly and steadily drill into the material, applying gentle pressure and using a steady hand to guide the hole saw. Make sure to wear appropriate safety gear and take breaks if needed to prevent overheating.
A hole saw works by rotating and cutting into materials using sharp teeth on its edge. The teeth create a clean and precise hole by removing material as the saw spins. The size and shape of the hole saw determine the size and shape of the hole it creates.
