Available in different diameters, these polishing sleeves adapt to a wide variety of applications, making them the ideal solution for stone fabrication workshops, countertop manufacturers, installers and professional stonemasons.

Designed for wet use, they maximize diamond performance, reduce operating temperatures and significantly extend tool life while producing exceptionally smooth surfaces ready for high-gloss polishing.
