Diamond Cup Grinding Disc

💎 Diamond Cup Grinding Disc — Shape & Refine Hard Surfaces

Choose a diamond grinding accessory for suitable glass, stone and ceramic projects. The cup-shaped metal disc features an abrasive working surface, with coarse and fine grit options for different stages of material preparation.

🔧 Choose Coarse or Fine Grit

Select a coarser option for initial shaping or a finer option for further surface refinement, according to the material and disc instructions. Check the selected variant for its actual grit specification; finish and material removal will vary with the setup.

💎 Electroplated Diamond Working Surface

Exposed diamond particles provide the abrasive contact needed to grind suitable hard materials. The coated working face supports surface preparation and shaping tasks where controlled material removal is required.

🧱 For Suitable Glass, Stone & Ceramics

Listed applications include glass, stone and ceramics. Match the disc specification to the exact material and task, and test on a spare piece before working on the finished item.

Grinding is a preparation step; additional finishing may be needed to achieve the appearance your project requires.
