4" Flap Discs

4" Flap Discs are utilized to increase productivity and reduce total grinding and finishing costs. 4 Inch Zirconia alumina discs use a high-performance abrasive medium delivering optimum performance on high-powered angle grinders at higher contact pressures and/or steeper work angles. 4 In Diameter Flap Discs are designed by layering coated abrasive flaps to wear away and expose a new, sharp grain. These abrasives excel in performance when compared to plain coated abrasive discs in terms of service life and grinding performance. Type 27 Flat Shape is great for use on miter joints, corners, and edges. Ideal for smooth finishing on intricate and ornate surfaces, the Type 27 SAIT Flap Disc has a zero to fifteen degree working angle.
