silver and deming vs. reduced shank?
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... |

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. Mike |

They were or may have been the first company to market reduced shank bits and the name stuck.........just like the name Weedeater actually a name of Poulans, but its associated with all string trimmers no matter who makes them.

Way back, before drill chucks were cheap and common, many post drills and hand drills just had a 1/2" round socket with a setscrew to hold a flatted round shank. Drill any size hole you want so long as your bit has a 1/2" shank. In fact I have a tray of old drill bits that have 1/2" shanks even though the bits are all *smaller* than 1/2". My Cole drill for example. So maybe that is why there is a special name for 1/2" shank drills. Bob |
