General purpose surface-conditioning discs optimized for use on all metals have an aluminum oxide abrasive. Surface-conditioning abrasives made of nonwoven nylon conform to irregular surfaces and remove surface imperfections, mill scale, and surface rust to create a smooth surface ready for finishing. Aluminum oxide is a strong, sharp, and durable abrasive that penetrates the work surface and withstands heat and high speeds. Example metals include mild and carbon steel, cast iron, cobalt, titanium, and chrome.

Coating-removal discs for use on thin-gauge metal have an extra-coarse silicon carbide abrasive. Abrasives for thin-gauge materials remove less materials than other abrasives to maintain the workpiece profile. Extra-coarse nonwoven coating-removal abrasives clean welds and strip rust, paint, and corrosion without modifying the shape of the workpiece. Silicon carbide is a sharp synthetic abrasive that provides a fine finish in low-pressure applications such as finishing and painting preparation. It breaks down faster than aluminum oxide.

Cool-cutting surface-conditioning discs for all metals have a ceramic abrasive. Surface-conditioning abrasives made of nonwoven nylon conform to irregular surfaces and remove surface imperfections, mill scale, and surface rust to create a smooth surface ready for finishing. Ceramic self-sharpens faster than other abrasives to remove material quicker. Quicker material removal speeds up the work and keeps the surface cooler, making ceramic a good choice for heat-sensitive metals. Example metals include mild and carbon steel, cast iron, cobalt, titanium, and chrome.
