Morse Taper Standard
The Morse Taper system was first introduced by the Morse Twist Drill and Machine Company and was based upon a taper-per-foot of 5/8 inch. In actuality, none of the Morse Tapers are exactly .62500 per foot, but rather range from .59858 to .62565 taper-per-foot. Stark Industrial standard 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.
