Silver & Deming drill bits are large bits ( > 1/2 inch ) with a 1/2 inch
diameter straight shank so they can be chucked in a standard 1/2 inch
drill press to drill large holes.  Watch speed and feed and they work
pretty well.  I use them fairly often in my 1/2 inch drill motor for
field work.
Most large drill bits use a taper shank and plug directly into the
drill press spindle.  They may need an adaptor for the correct taper.

They are the cut down shaft type of drill bit. All typically have the
shaft cut down to 1/2" diameter. I think originally silver  and demming
was a trade name, that has stuck though the ages....

they were  intended originally to fit in a 1/2 straight spindle hole, in 
blacksmith's drilling posts, I belive.

Roy,
	D&D bits are reduced shank bits, for instance a 3/4" bit with a 1/2" shank

All the ones I have seen are made in China.

Then I'll have to admit to some lousy humor, as I use sets of drills in my
home shop from foreign shores... for mild steel, aluminum, etc, I have no 
complaints.  For heavy duty use (like when I drilled 112 5/8" holes in a piece
of 8" pipe for the Otter's new boiler), the industrial made in USA stuff is
just right, stays sharp and is a pleasure to use.

If you work with stainless, etc, do yourself a favor and buy good quality
cobalt drills.

I not sure, but I've always thought they were named after the

Well, I have some Silver & Deming drills from 1/8" to 1/4", but they all 
have the same size shank.

Rubbish, plenty of good  cutting tools are made in other countries, 
including my own, Canada.  If you buy cheap tools, you get what you pay for.
Inexpensive doesn't have to mean cheap.  Over the years I have had a 
number of US made tools that were junk, and some good ones too.  The same 
goes for some of the British & Canadian tools I have owned.  I have a 
couple of Canadian made taps that were used for more than 50 years in a 
motorcycle shop, they are still in good shape.  My Canadian made 
Butterfield 1/2 inch reamer has seen 25 years service in my shop, it is 
well used, and still in good shape.

Somewhere I read about this. It seems like there used to be two
companies, Silver for one and Deming for the other that made similar
drill bit products. They merged to Silver and Deming, and the bits
inherited the name. I could have dreamed this, too.

     I have wondered about that myself. After trying to drill a hole
with my brothers 'extreeeeeemly cheap' "imported" Silver & Deming
3/4" drill bit I have come to the conclusion that (at least in this
case) it means "drills ground with no back clearance", no kidding
the thing was ground to a cone shape on the end, correct angle but
nothing else.

Steve,
>including my own, Canada.  

Right you are.  The problem (and it IS our problem(that is the people 
of the USA)) is that most people here in the states actually forget 
about our friends to the north and accross the Atlantic.

Silver and Demming drills have 1/2" shanks on them. For a large drill, like 
1-1/2", it makes it a lot easier to hold in an arbor.

It's even worse than that.  I think most people here don't even think 
of Canadians (or at least Canadian products) as "foreign."  That's good 
in the sense that they get equal treatment, but my Canadian friends get 
quite stuffy about pointing out they have their own country even if it's 
just over the horizon.

   Actually, I've gotten a load of aerospace- and auto-industry bits and 
tools and a lot of them came from Canada.  I don't think they were 
cost-cutting over at Boeing or Ford when they bought them.

   As far as the Brits are concerned, it's like the man said: you get no 
more than you pay for (and if you're careful, no less).  Certainly 
world-class if you pay the price, garbage if you pay garbage price.

Typical USA-centric view of the world. I got quite a few nice drills made
in Sheffield England where they were making drills before there was a USA !
(You're right about E.Europe and the far East though).

>(You're right about E.Europe and the far East though).

Sorry if my attempt to insult foreign shitty cutting tools was taken the wrong 
way be certian Canadians and Englishmen. Actually, I didn't realize any of you 
even made cutting tools. Around here you have a choice between American(good),
Jap(pretty good), isreal(shit), Polish(shit), Chinese(shit), Spanish(really 
shit).
I was going to revise my statement to any country where the people speak 
english has good cutting tools, but now I'm  not sure if the USA qualifies.
Be that as it may, I think you all know what I ment.
