Modern sanding pads for grinder are made of man-made synthetic materials like ceramics, silicon carbide, and aluminum oxide. Higher-quality circular sanding pads are produced as a result of the increased control that man-made materials provide over tolerances, capabilities, and dimensions. These materials can be precisely formed, will maintain their grinding abilities for a longer period of time, and have superior heat resistance, enabling them to survive extremely high RPM.

Type of Sanding Attachment for Grinder

Fiber Sanding Disc: These are suited for general-purpose tasks like surface preparation and hard grinding. Heavy duty coated grinding discs for resin fiber sanding discs are designed for use with backing pads on portable angle grinders in the manufacturing and industrial sectors as well as for painting and rust removal, deburring, portable grinding, and cleaning.

Flap Discs: Right angle grinders can be used with flap discs to grind and finish simultaneously since they have abrasive flaps attached to a sturdy backing plate. They work well for beveling, finishing, cleaning, and detailing tasks as well as for removing stock and materials during blending work.
