Silver and Deming is a design of reduced-shank bits invented by
Albert Silver and John Deming in the 19th century.  The name "Silver
and Deming" was adopted by many manufacturers for this style of
bits.   They are six inches long with three-inch flutes and a
half-inch shank, diameters run at least up to one inch..  You can get
good ones and bad ones.
