I need to drill about 4 or 5 holes of around 3 to 4 mm in some stainless. It's not very thick - 0.5 mm perhaps ? Certainly not more than 0.75, anyway. It is good quality stuff though, and *very* hard. It's actually a stainless steel professional kitchen prep table. The last time I tried to drill anything similar, I wrecked a number of drills in short order.
The holes I need to drill are in a vertical surface, which doesn't leave any easy options for any kind of lubrication or cooling. So, the question is, is there a type of drill bit that will go in a standard (decent) DIY quality electric drill, and will survive long enough to drill this small quantity of holes in this material, and doesn't cost an arm and a leg ?
Pointers to specific items from anyone with experience in working with this difficult material, greatly appreciated.
TIA ! :-)
