At work a guy is reaming out a hole to a larger size in a frame rail
on a truck. His reamer starts squealing like a banshee. I say, "Hey,
how about a little cutting oil?"
He looked at me like I was an idiot and told me that it'll dull the
reamer and take chunks out of it in nothing flat. Everyone else in the
shop agreed. But nobody could explain to me how or why, only that it
would happen.
So am I missing something here? I thought reaming required cutting
fluid, but now I hear from a whole crowd that does a fair amount of
reaming that it's just the opposite.
The reamer in question is basically 2743A14 at mcmaster.com Perhaps
these things follow a different set of rules?
Also, is it possible to salvage one of these once it's dull without
resorting to anything beyond hand tools?

Obviously they are very mis-informed.

Don't think so. but there are places that will sharpen them.

I think a better one for you would be:

I bet they have a *lot* of dull reamers where those folks work.

Note: never lend them any of your reamers.

Using lube oil on reamers is bad. Turning them backwards is bad.
Running them too fast, is bad.

I BOUGHT A TRUCK FRAME REAMER 10 OR 15 YRS AGO--3/4" DIAMETER W/ 1/2"
SHANK & 3 FLATS.. THEY RECOMMENDED THEIR SPRAY CUTTING
LUBE/COOLANT..BEST BUY I EVER MADE.--Can is long gone, but I remember,
the reamer would immediately start cutting faster & easier & you didn't
have to slow down till you were done! With a spray can you get even
coating (cooling) and the waste is practically nil, especially with
a 2nd person helping.

Obviously they are very mis-informed.

Naw! They meant the oil would leak down on the hand drill motor and make it
go faster and tear out larger chunks.

fluid, but now I hear from a whole crowd that does a fair amount of
reaming that it's just the opposite.

At work, I sometimes have to hand drill holes up to about 1/2" in cast iron,
mild steel, cast tool steel, etc. for hours.

You should try using lube and see what happens. While using lube on a drill
press is not a big deal, the amount of control you have using a hand drill
is much less. My drill has a safety clutch as it has an electronic speed
control and is easily capable of breaking my arm, but many do not.

Perhaps allowing the reamer to cut more freely will cause it to grab (and
then you're done).

BTW, if you're interested in a nice electric hand drill, check out the
Metabo BE1020. I can't say enough about this unit. Worth the $320 Cnd. every
time I use it...
