Or you can turn the reamer backwards and use the sandpaper.


An old wives tail truth is your only going to dull the fucking thing if you
try and do it that way--in fact you'll be lucky if it doesn't sieze in the
first hole.

Best to just buy the right size in the first place.

Sure is. But sometimes we get a rush job and we can't wait to order
the right size. And sometimes the right size one cuts a little big or
small anyway.

it works for me. Sometimes too well. Then I have to scrape up a burr
on one or more flutes to make it cut bigger again. Never had one
seize.

They just fracture.

Never had that happen to me.

Having a 1.5 inch one fracture into spinning shards can be interesting.

Then there's the poor *** that later inherits your *** reamer....

I usually toss them after the job. Not worth the trouble to save them
unless a very short run.

I guess you don't pay for them.

Nope. That's the boss's job. I just do as I'm told.
If he wants me to mess around with crappy reamers that are in all
states of wear,

Send them out to be sharpened when they show hint of wear.
Most are designed to be resharpened and they are expensive.

loose in a box, un-marked,

The size they cut (in what material?) should be etched
on the shank IIRC.
And who dumped them in a box???
Put back in the original shipping tubes, etc.
DON'T let them bang into other tools !

well that's fine by me(I
get paid by the hour). Or we get new ones, and toss them if they
wear out, or save them if they don't.

If you can see a small radius worn on the cutting edge it's
time to resharpen.

And there you go again ... no proper (not ruined) reamer in stock so you
hack-n-whack, right?

I work with what I have at hand.
It would be nice to have a fully stocked set of reamers when I need
one, but that's not how it works here.

See above. You've been tossing them.
Check out prices.

Now, about your feedrates .. ? Most underfeed their reamers IIRC.
