Import Diamond Brush — Buy in Bulk from Supplier in China

The diamond brush offered by Zhonglong Indusrty Co., Ltd is designed for stone processing, especially granite finishing. It features a high abrasive quality that enables efficient material removal without heavy machinery. The tool is compatible with standard polishing machines and can be used directly on a variety of granite surfaces. Its construction allows a consistent finish that meets typical industry expectations for polished stone work.

Diamond brushes normally employ metal‑bonded diamonds with grit sizes ranging from 100 µm to 200 µm, which is considered typical for granite applications. The bond provides sufficient rigidity to hold the diamonds during high‑speed polishing while allowing controlled wear. In the stone‑working sector, such brushes are frequently selected for their ability to produce a smooth, mirror‑like surface on hard stones. The brush dimensions are generally around 300 mm in length, a size that fits most standard machine heads.

Primary users include stone fabricators, countertop manufacturers and restoration contractors who require a reliable finish on granite countertops, tiles and monuments. Buyers usually request verification of ISO certification and may negotiate FOB or CIF shipping terms. Minimum order quantities are not disclosed in the listing, so interested parties should confirm the MOQ with the supplier. Payment methods commonly accepted are L/C and T/T, though exact terms should be agreed before order placement.
