1.Products with high strength, high melting point, chemical resistance, strong resistance;2. Grinding the hyperboloid and concave-convex surface fully and uniformly;3. High durability, resilient bristles, won't break off, absolute wear well, and reduce the polishing time to improve equipment efficiency;4.Good acid and alkali resistance, resistance to chemical organic solvent, without destroying the original surface light solubility;5. Low water absorption bristles, suitable for wet and dry grinding. Better use it adding some water, make the wire cooled to get harder and more wear-resistent.1. Suitable for surface finishing of woodworking, furniture, carved rosewood furniture, three plywood; the complex furniture's wood grain processing, concavo-convex surface grinding operation.Easy to use without polishing wax, because of the abrasives inside.2. Also can be used for other materials, for deep holes deburring; surface grinding before plating and coating; decontamination and grinding of copper plate in electronic circuit board;3. Removal of burr and chamfering after machining; surface grinding of die-casting parts,etc.color: blueMaterial: NylonPackage Content: 4* Polishing and polishing brushOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
