Indalo yediski edityanisiweyo yendalo esingqongileyo engama-28:

Idiski enesingxobo enobuhlobo kwindalo esingqongileyo yenziwe ngamalaphu akhethekileyo e-emery abotshwe kumhlaba olungele indalo. I-disc ye-SG enobushushu bendalo (eluhlaza okotshani) ebonakala ngokhuseleko oluphezulu kunye nokuguquguquka okuhle; ilaphu le-emery kunye ne-substrate zombini zinobuhlobo kwindalo. Izinto ezisetyenziselwa ukupolisha amaqhuma e-welding kunye nepeyinti umphezulu weenqanawa, iimoto kunye neenqwelo moya.

Indalo yediski edityanisiweyo yendalo esingqongileyo engama-29:

Idiski yesanti edibeneyo yendalo esingqongileyo yenziwe nge-zirconium corundum abrasives, iiceramic abrasives kunye nesiseko esixhasayo. Imveliso inefuthe lokupholisa xa isambatho esikhethekileyo sinentsebenzo enkulu yokusika. Ingasetyenziselwa ukugaya isinyithi ngokubanzi kwaye ikwalungele ukugaya nokuma okumanzi.
