Interesting tip.
Will a torch with MAP gas get it that hot, or do you need acetylene?

If someone gets a bit too hot and it loses its hardness, you can heat
it up to cherry red, hold for a minute and then dunk in motor oil.
Good trick for old chisels too.

i quit caring about installers having good bits the billionth time i
told them that you dont use them on rock, and if you are using rock
with the right bit or not you need a hammer drill, and no, your impact
isnt a hammer drill, and your long bit goes back in the tube, not on a
pile of gear on the floor. F those tower monkeys, let them get their
own bits

Aluminum can be worked with wood working tools, no problem. I use

One tip I learned after ruining carpets in double wides. Put the
drill in
reverse when drilling through carpet.

When I did installs every day I would use the same 5/16" drill bit for
6-12 months. I know I could have sharpened them, but it was easier to
just get another one at Lowes.
IMO drill slower so it doesn't get too hot. When you're going through
metal set the drill on the lowest speed and use moderate
pressure. You
want to see little flakes coming off the metal rather than dust.
If the
metal is thick then put some oil on the bit to conduct heat away.
WD-40
will work in a pinch, or a little can of 3-in-1 oil with the dropper
tip. Even on wood, don't go full speed unless it's a short hole.
When
the wood is real chewy you might have to back out and in to clear
debris
and let the tip rest. If you're getting smoke you're trashing that
bit. Aluminum siding is so thin I can't believe that's what ruins
your
bits.
