mine's variable but I don't vary it very much and right now I think it's
set to ~2000 rpm

What's yours set to? And do you vary it often?

It's like the lathe and speed depends on the wood but so far I've not
had any problems. I got a fair bit of steam when drilling wet wood
but I don't think lower rpm would make a difference

I rarely use any of my drill presses for wood, but I set the speed based on
the material and the bit size. On my no-name mill drill I leave a 5/8 bit
in it for drilling out low pressure injection mold ports, and leave it set
at its slowest speed. On my floor model I drill a lot of .250 (+/-) holes
in aluminum so I leave it set around 2.8K. If I use a larger or a smaller
bit or drill some other material with it I open the belt lid, and look at
the speed table list for materials and bit size. My bench top drill press
only ever gets used for my tapping head, so it gets left at its slowest
speed as well.

Most of my odd drilling is done on one of the CNC mills, and every single
operation is calculated for a solid conservative speed and feed based on
material, bit size, horsepower, bit strength etc. Well, except stainless
which I try to drill as aggressively as practical so that it doesn't work
harden on me halfway through the hole.

620, as slow as it can go. Works fine for small bits in wood
(it's still a lot faster than I can crank a hand drill), and
I don't have to remember to slow it down for a big forstner.
I don't remember the last time I changed it.

I use mine whenever I can. I like my holes to be at right
angles to the surface of the wood :-)

I typically keep my DP set at 750 and lower. Most of my holes are
drilled 1-3/8" for Euro hinges.

Right now it's set to 844, as I have been drilling a lof of small holes
in wood. Usually I leave it at 350 or 500, which is good for metal up
to about 1/2".

I'm pretty lazy about changing it, unless I really need to/should.

Do you ever use boring bars for wood? this might solve a problem
I have with drilling deep holes in wood

Well, except stainless which I try to drill as aggressively as
practical so that it doesn't work harden on me halfway through the
hole.

do you mean the stainless gets hard when you start to work it?
I didn't know that

840 sounds better 2000 is not a good set it and leave it setting

Yep me too

0 rpm. I vary it quite often.

The control is actually set rather fast... something like 3600 RPM.
Since it's adjustable via a speed control lever, I do vary it quite
often. Sometimes it makes a difference, but never has a bit refused to
work because of improper speed.

You might consider withdrawing the drill bit more often. Wet wood will
tend to stick, so you'll be slogging along chips as well as attempting
to get the end of the bit to cut. A little wax might help as well.

Settled long ago that 1200rpm seemed to work best on this particular
machine and for what I do.

And do you vary it often?

Occasionally, depending on both the material, but deciding factor is
whether I'm not getting the results I want.

If you get it blue - you will have some serious crystals grown
that are chrome oxide. Hard stuff - Green stones grind it out.
