Hi,

I was going to ask what a "silver and deming" drill was but thought an
Internet search was in order first. So, I found out that "silver and
deming" comes from the name of a company that was the result of a merger
between the Silver Manufacturing and Deming Manufacturing companies. So,
now I know that "silver and deming" has nothing to do with what the drills
are made of, or for...

But I still don't know why some manufacturers sell "silver and deming"
drills while others sell "reduced shank" drills. What's the difference?

Oh, wait a sec... is it that "reduced shank" drills are reduced down to
fit in a 3/8" chuck and "silver and deming" drills are reduced down to
1/2"
??? Or, is it just some traditionalist verses modern naming convention?

It's no big deal... I use M taper drills but I am curious.

David...

Strictly speaking, a "reduced shank" is just and only that. Reduced to
whatever size is needed/wanted/will sell.

A Silver/Deming is reduced to 1/2" diameter and may or may not have three
jaw flats ground on them.
