• Grind and finish: Can remove material as aggressively as a 24 grit depressed center wheel, and then blend in a "ready to paint" finish like a sanding disc
• Flexibility: Flexes to follow contoured surfaces, a smooth finish with no gouging
• Versatility- no loading, no glazing: one specification performs on a wide range of materials, no loading on soft material such as aluminum plus no glazing on hard material such as stainless steel
• Long life and economy: has an impressive ratio of material removal
• M (medium grade) : general purpose, metal grinding/finishing comparable to 24 through 60 grit sanding disc
• Iron-free: for steel, stainless steel and aluminum
