I needed to drill several 3/16 holes through 1/16 stainless steel. My 3/16
bit was good for one hole, then I had to switch to a 11/64 for the next
hole. These are gold colored (titanium nitride coated) bits. So can the
experts here tell me what type of bit to use or does the face of the bit
need a different angle to cut better?
Slow speed and coolant will help. Wd40 if nothing else is available. Also
you can try sandwiching the plate between two pieces of scrap wood and drill
through the top piece through the metal and just into the under piece this
will help with heat dissipation and keep the burr size done on the out going
side of the cut. When your hole is wider than the part is thick this is a
good way to work, it also cuts down on the number of spinning things that
can make there way up the drill bit and turn into airplane props.
Did you even bother to look? or do you need to be spoonfed?

Drilling Stainless Steel I want to drill a 1.25" hole in a sheet of

not sure of the grade but it's the type commonly used for commercial
range hoods and tables. How do I go about this? Hole saw? Carbide

wood drill bit versus metal bit ... the first choice. Brad points
are sort of flat tipped but have a point
in the center. When drilling stainless, it is best to spray on some
sort of lubricant. WD-40 or a light oil will work. Ed

Best way to drill hole in stainless steel sink deck I used a bi-
metal hole saw....the steel didn't melt. Consider some drilling oil
or lubricant.... Sue You may consider using a "knockout set". ...
Drilling at high RPMs
will cause steel to melt and the bit to weardown quickly. Hope this

drilling through ceramic tile ... It took about fifteen minutes to

ceramic tile, it
looks like a blade rather than a standard drill bit. Haven't tried

I didnt have the time to read all of this book you wrote here, but to
make holes for a faucet or other fixture in a SS sink, I take a drill
and drill a starter hole that will fit the cutter. Then buy cutters
made for electricians that cut 1/2" 3/4" 1", etc holes in electrical
boxes. They are called Greenley. They cut large holes well.
We use them all the time in the machine shop. They are only junk when you
use them improperly (high speed when the material calls for low speed).
Cobalt bits are stronger and cut harder material, but also brittle so don't
drop them or try to twist them in a hole to widen the hole.
Cutting oil, not water. Otherwise any oil will work. High speed steel does
NOT mean you can use high RPM. My machinist handbook is not handy (packed
away during our move), but drilling with a HSS bit in stainless is only
about 60fpm compared to drilling aluminum at something like 500fpm.
Translation for 3/16 would be somethign like maybe 200 rpm versus 1200 rpm.
You can drill MUCH faster with a cobalt drill and the drill will last much
I drill stainless all the time, up to 1/4" thick. 3/16" is one of the
more common hole sizes I drill.
Only way to go is cobalt bits in a drill press. Can also be used in a
portable drill. A 3/16" cobalt bit is about $4 at any hardware store.
As others have mentioned, slow speed and lubricant is required for SS.
