Standard Taper Flanged Wheel Adapters.
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER. FOR 1.250" ID WHEELS.  DESIGNED FOR THIN CUT-OFF WHEELS AND DIAMOND WHEELS.


Sopko flanged adapters are machined from alloy steel. The resulting one piece hub design distributes mounting pressure away from the bore, the weakest part of the grinding wheel. The inherent rigidity of one piece design, and the precision ground flanges provide identical radial load bearing surfaces for positive wheel lock and better spindle driving torque to the abrasive wheel. All surfaces are ground concentric and square for optimum surface finishes. Completely heat treated, Sopko flanged adapters are safe to use and maintain their rigidity.

Standard Taper Reversible Wheel Adapters.
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER.  DESIGNED FOR 1.250" ID DIAMOND, CBN, AND VITRIFIED WHEELS.


THERE IS A DIFFERENCE WITH SOPKO REVERSIBLE ADAPTERS!

  • Formed wheels are used either way without redressing.

  • Can be REVERSED without DISMOUNTING the wheel for prolonged square corner life of diamond wheels.

  • Sopko reversible wheel adapters make it possible to use the same dressed angle for
    BOTH RIGHT AND LEFT GROUND TOOL BITS.

  • EASY TO USE-Just remove the adapter from the spindle nose and REMOUNT in the reverse direction.

  • SAFE TO USE-Sopko reversible wheel adapters are manufactured with a double-taper and are securely locked against loosening by the wheel rotation.

  • Manufactured from quality steel to withstand the rigors of daily use, then HARDENED and GROUND.
     

For use on all spindles having a 3.000" TPF with 1.00" diameter at large end of taper.  Including: Boyar-Schultz, Bridgeport, Brown & Sharpe, DoAll, Excello, Foote Burt-Hammond, Harig, Norton, Parker Majestic, Pope, Reid, Sanford, Setco, Taft Pierce, and Whitnon.

A precision ground double-taper and removable bushing make wheel mounting in opposite directions safe and reliable. Grinding wheel edges wear during use, but obtaining a new sharp edge is as easy as reversing the adapter on the spindle. LH thread is standard.
