This fast working disc combines the upper cutting action to the fast fixing system 3MTM RolocTM to clean, strip, drool, melt, finish, polish, scratch and remove rust and coatings efficiently and without damaging the basic material. In normal use conditions, the bristles remain firmly in place and can get the desired finish with a slight pressure. The Scotch-BriteTM RolocTM bristles disc works well on steel, aluminum and other metals, for general maintenance, as well as automotive and engine reconstruction applications. The abrasive ceramic grana 3Mtm is a ceramic mineral made with our proprietary process to increase the strength and hardness of the grain. For better performance, Scotch-BriteTM bristles are made of aluminium oxide mixed with abrasive ceramic grana to create one of the most durable and durable minerals available. Perfect for removing moderate to heavy material, ceramic abrasives are designed for quick cutting and handling applications with intense heat and stress. The abrasive ceramic grana 3Mtm surpasses aluminum oxide abrasives for cutting speed and durability and is an excellent choice for industrial sanding and finishing. Scotch-BriteTM abrasives are exclusive products for surface conditioning with integrated abrasives in nonwoven fiber matrices. Combining abrasives and nonwoven material creates an abrasive system that gives constant results throughout the product life. This open mesh material works cold and is load resistant: preserves the high cutting performance of abrasive minerals by limiting fiber obstruction.
