Ever try to drill through stainless

Fuck me

Sure… many times. Junction boxes, plating, shelves… you name it.

The one thing I’ve found is that the type and quality of bit have little effect. A high-end titanium bit will fair as poorly as a .$1.50 Buffalo bit. The key with drilling any solid metal is to first make a dimple in the surface.

I am talking about the real thing not some light alloy junction box - I could piss thru that

Never.
