llB Advantages of the Pratt Burnerd Multisize Collets WIDE RANGE CAPACITY Each multisize collet has a gripping range of 125" with an extended range of .010" above and below each nominal size for a total range of .145" per collet. ADAPTABILITY Fractional, decimal, metric and non-standard bar sizes are all accommodated as the collet range is stepless. The collets will accept
round and hexagonal bars. UNEQUALLED ACCURACY Each collet is inspected to .0005 maximum eccentricity at the nose of the collet. NO DISTORTION Geometrically designed. Ensures freedom from collet distortion and provides constant parallel grip throughout the gripping range with even wear and long life.
ALL STEEL COLLETS Collet blades are all hardened and ground.
