I don't have any Stainless steel to try it on. Just as rock is not listed as an application, it may work. Experiment like I did. It's only a twelve dollar risk.
I believe it will. I just drilled some very old/hard concrete with it and it worked great. I powered it with a DeWalt 20 Volt hammer drill.
Not a good design for use on metal.
Yes
NO. The carbide chisel tip on these drills is for concrete/masonry. Use a HSS (high speed steel) twist drill to drill out the broken anchor. It may take several drill bits to complete the task, usually the bit will rub on the concrete hole side during the process and dull the side of the bit.
NO. This is a very difficult task. It is possible to do with a carbide twist drill at low rpm's and patience. Ideally you would use a a LEFT HAND carbide twist drill because the direction of rotation will tend to back the broken tap back out. If possible, set this up in a drill press so you have the best control of the carbide bit; any side force will break them. Carbide is very hard, but also brittle, so keep the drill bit as straight as possible if you attempt this with a hand hand held drill motor.
NO.
Not recomended because it will tend to shatter the tile. Use a carbide SPADE BIT, they will cut a nice clean hole in tile without breaking it.
A better option is the Bosch 1/8 in. x 2 in. x 3 in. BlueGranite Turbo Carbide Hammer Drill Bit for Concrete, Stone and Masonry Drilling model # HCBG01T.
Home Depot carries actual stucco screws, called "Stucco Anchors" that come with their own bit, and they work really really good... short of that a masonry, carbide, or this type works fine, you're basically drilling grout with wire in it...
