Brown & Sharpe Taper Extended Length

 Brown & Sharpe Tapers were introduced by the Brown & Sharpe Manufacturing Company and have a nominal taper-per-foot of 1/2 inch. In reality, the tapers are not exact to the specification, but range in size from .49973 to .51612 taper-per-foot. Stark Industrial extended length centers are made of bearing quality 52100 steel, heat treated to 60 - 64 Rc, and guaranteed to have .0002 or less total-indicator-runout. Also available are standard carbide tipped centers with 52100 steel shanks hardened to 45 - 50 Rc.
