What are the primary applications for these 80-grit white aluminum oxide discs?
The 80-grit is ideal for aggressive stock removal, weld seam leveling, and heavy-duty deburring on metals like steel and stainless steel. The white aluminum oxide abrasive is a premium material known for its durability and cooler cutting action on hard metals.
