My client is now in contact with Cogsdill sales engineers and the project
may go in that direction. So far it promises the best in initial cost and
actual operations... will see.

Hey Joe, not to be contrary or anything but I just finished a job that
had .244" dia holes going through a .500 dia aluminum part. Deburring
the hole with a regular countersink doesn't work bery well. But the
spring loaded Cogsdill Burraway worked great. The secret is using a
tool that fits the drilled closely and messing with the setscrew that
controls tension on the blade. These joles were on the O.D. of the
part. I.D. holes can be harder to deburr right so your suggestion of
having as small a burr as possible by controlling the feed is a good
one. I have rounded the first cutting edge on the Burraway tool. This
is so I can deburr the inside of the hole without doing anything the
the outside. Sometimes the jobs I do require minimal visible edge
breaks for cosmetic reasoms.

Great to learn about these tools from someone who has used them! Thank
you
for the insight. We are always getting inquiries on hole drilling (that's
what we do!) and deburring operations... One of these days, I'll simply
buy
one of their tools and test it on various materials, tubes, etc. for some
first-hand experience too.

Cogsdill makes a burnishing tool which is pretty cool. We use ot for
some
oil impregnated bushings on our machine... I am pretty sure they are made
to be used on a drill press, etc. but I've put a handle on them and use
them
manually. Great quality tooling IMHO.
