I need to drill the 2" diameter holes in the Stainless Steel firewall
around the engine mount attaches.  Does anyone have technique that works
well ( note the holes must be drilled with the S.S. attached to the
firewal)l.

I saw some carbide tipped hole saws at Home Depot last weekend ( approx.
$26 ).  Would these hold up against the Stainless for 6 holes?
