Has an end with a smaller diameter for a ways than the rest
of the shank, or, some kinds of them have as little
'stairs', where, each level of ascent is a slightly larger
diameter.
Slow rpm and lube it well...regardless...
Stainless is a tough alloy, and many drills as one may have
for general tasks, shall not like trying to drill it.
Also...I suppose, if drilling through the stainless steel
sheeting or band of a Kiln, if possible, it may be worth
while to introduce a scrap of plywood or similar, so the
pressure one may be putting on the drill bit does not
localize so much as to deflect the metel and push against
the brick in some way as might break it. Just see if some
scrap of plywood or thin wood may slip in there to spread
that force a little better...
