Item Name:
Covington Parts - 6" Diamond Sanding Disc Set with Plate
SKU:
13-225
Description:
The 6" Diamond Sanding Disc Set w/Plate is a coldworking sanding system built around a rigid 6 inch backing plate that supports interchangeable diamond abrasive discs. The plate provides a flat, stable surface so the discs run true, which is critical when you are flattening glass, truing edges, or removing saw marks without introducing waves or low spots. In lampworking and general glass finishing, this type of set is used for shaping and refining the coldworked surfaces of marbles, pendants, components, and small flat work, especially when you want consistent contact and predictable results from grit to grit before moving into final polish.
How it is used:
- Install the backing plate on the correct lap wheel or arbor for your coldworking setup and confirm it runs flat and stable.
- Run water during use to cool the glass and to flush away grinding residue.
- Start with a coarser diamond disc to remove chips, level a surface, or true an edge.
- Progress through finer diamond discs, removing the previous grit scratches completely before moving up.
- Finish by moving to your preferred polishing step after the finest sanding stage, depending on the surface quality you need.
- Clean the work area and rinse the glass between grit changes to prevent contamination that can cause deep scratches.
