Diamond Grinding Cups

Diamond Grinding Cups — DiStar & Weha

Diamond grinding cups are the essential edge-finishing and surface-preparation tool after cutting — removing chipping from saw cuts, shaping profiles, beveling edges, and producing a smooth consistent surface ready for polishing or grouting. Pro Tool Haus carries both the DiStar DGM-S range for tile and porcelain edge work and the Weha cup wheel range for granite, engineered stone, and multi-material grinding.

The DiStar DGM-S range uses a segmented geometry calibrated for ceramic and porcelain — Soft Edge for standard-hardness tile, Hard Ceramics for ultra-dense sintered stone — in 2" and 4" sizes compatible with both standard angle grinders and Proxxon long-neck tools. The Weha cup wheels cover resin-filled cups for chip-free grinding, rubber cup wheels for flexible surface contact, flap cup wheels for blended-finish grinding, and the Pitbull hybrid for backing removal and heavy material removal.
