Used in polishing metallurgy, machinery, light industry, wood products, furniture, metal, plastic, melamine, building materials, automobiles, textiles, and other industries. Especially suitable for uneven curved surfaces, good dissipation, do not burn the workpiece, can grind the fine grain. The unique structure of effective dissipation, to prevent discoloration and deformation due to overheating in the processing process of the workpiece. The processing effect remains stable and consistent, and the shape of the workpiece will not be damaged by excessive. Good self-sharpening, continuous loss of fiber in the grinding process, the mineral grinding continuously natural formation, to provide consistent quality of the workpiece., Weight: 0.42328754304 Pounds, Manufacturer: Rtxbvg
