These discs are designed for challenging applications, offering superior durability and extended lifespan. The tough, self-sharpening zirconia grains make them ideal for aggressive grinding and sanding on tough metals and other hard materials. They maintain their cutting efficiency for longer periods, making them suitable for industrial and high-performance applications.

Applications: Weld preparation, deburring, and smoothing rough surfaces; removing rust, scale, and tough coatings from metal surfaces; heavy stock removal on hard and soft woods.
