Mirka RFD 5 x 7/8 ZIRC 24 grit 25/Pkg

Our longest lasting fiber disc, the special zirconia formulation out-performs standard red fiber discs 3-1 for high production stock removal. Harder than aluminum oxide, its self-sharpening properties keep it cutting longer. Fiber discs are extremely durable, suitable for difficult surfaces. Firm dust binding properties make them perfect for removing topcoat, rust or for grinding down welding seams.
