Selection Notes

How To Choose The Right Grade

  • For ball polishing, particle shape regularity controls roundness far more than the nominal size does.
  • Carbide parts are prone to cobalt leaching — ask for the surface-treatment option when the binder is cobalt based.
  • For honing, the bond system and the grit size have to be chosen together; we quote them as a pair.
