Took possession of the following punch this morning:

Had to place it on the floor and lean on the handle slightly in order to punch the holes, but they came out beautifully.  Re-cut my bracket in a fraction of the time it took the first time round and even modified it to take wider snare wires.  My snare drum sounds great now and the job was neat (I can sleep soundly again).

When I used to drill RACO boxes, the keys to successful drilling were:

1. Clamp the work.
2. Use a slow drill speed.
3. Use a high quality and sharp bit.
4. Lubricate the bit.

It's easier with a drill press but I used to hand drill them too, with good results. I punched a dimple in it with a nail set first to center the bit too (which I also do with aluminum).

I don't know how any of this relates to stainless steel.

I don't know how any of this relates to stainless steel.

If my experience is anything to go by, you end up with very blunt bits, a very hot drill and barely a dent in the material!

Having Done some machine work as an auto mechanic, the best things you can do are simple good sharp bit suited to the material, cutting oil or 3 in 1 oil, basically any light oil will do adequate pressure, and lots of patience.
The one shop I worked in we drilled a lot of hardened steel shafts, and even with all the conditions right it could take a while,
Don't buy drill bits made in CHINA guys, they lose their edge very rapidly, and they tend to break. High quality european or american made drill bits esp for metal work, Hard materials call for a sharp bit and american and european bits are hardened after they are sharpened so they hold. Asian Manufactured bits are not (cost cutting Measure)
have fun and Happy Drilling!
