Blue color Material: Nylon Package content: 4 * polishing and polishing brushes 1. The product has high strength, high melting point, chemical resistance and strong strength; 2. Hyperboloid and concave-convex grinding surface, completely uniform; 3. High durability, bristles are elastic, not shedding, wear-resistant, reduce polishing time, and improve equipment efficiency; 4. Good acid and alkali resistance, chemical organic solvent resistance, without destroying the original surface light solubility; 5. The bristles have low water absorption, suitable for dry and wet grinding. It is better to add water when using to cool the wire to make it stronger and more wear-resistant. 1. It is suitable for woodworking, furniture, carved rosewood furniture and the outer surface of three plywood, complex wood grain processing of furniture, and concave and convex grinding operations. Easy to use without polishing wax thanks to the abrasive interior. 2. Can also be used for other materials for deep hole deburring, surface grinding before electroplating and coating, decontamination and grinding of copper plates in electronic circuits, etc. 3. Deburring and chamfering after machining, surface grinding of die-casting parts, etc.
