GARNET SAND 80MESH FOR MARBLE/PORCELAIN/CERAMIC TILES/STAINLESS STEEL CUTTING
Rock garnet sand is a sharp and tough abrasive material in a reddish tone. It is produced as a result of crushing rocks. The mineral is chosen and processed into a product of the highest standard. It works best as a waterjet abrasive medium.It’s hardness is tied to garnet’s mineral structure and hence it gives a high durability. That’s why Premium Rock ensures a stable work of the WaterJet machine for the whole time of it’s use. Sharp edges of the grains provide high quality and smooth aftercut surface. This abrasive sand also guaranties the best cutting quality with thick materials.
