  • A K.O. LEE Expandable Mandrel is a time-tested tool for grinding, turning and milling operations.
  • Built for a machine like Expanding Mandrels lathe or Expanding Mandrels mill, Expanding Mandrel workholdings will hold work from thin sleeves and bushings to heavy casting and forgings. K.O. LEE’s mandrels are sized to fit 3/8″ to 5 1/2″ (9.5 to 139.7mm) holes.

    There is a K.O. LEE expanding mandrel set for every shop. Any mandrel may be purchased separately for production operations. A full set of K.O. LEE expanding mandrels will eliminate making and stocking separate mandrels for every job.

    A large bearing surface on all sleeves provides a positive grip on heavy jobs, prevents slip and chatter and holds thin sleeves and bushings without distortion. Work can be held in any position on sleeve and may overhang on either or both ends for facing operations.
    Precision ground arbors and sleeves provide accuracy of 0.001″ (0.025mm) or better. Large bearing surface minimize wear.

    Auxiliary centers are a K.O. LEE feature, providing a large bearing surface and oil reservoir. The auxiliary centers also prevent damage to arbor center, prolong arbor life and are inexpensive to replace.
