Composite-backed universal flap discs
Milwaukee, Wisconsin – PFERD Inc.’s POLIFAN PSF Z-TRIM (PFE-121A) universal flap discs have a light weight composite backing that can be trimmed to extend service life and reduce time-consuming disc changes. The composite backing and flap arrangement reduce vibration and noise levels. Produced with a higher density of zirconia-coated material (Zirconia alumina Z) than standard PSF flap discs, these discs provide an improved surface finish and cushioned, contamination-free grinding in surface grinding, weld grinding, blending, chamfering, and deburring on steel and stainless steel (INOX).
Premium zirconia self-sharpening abrasive grain produces high stock removal rates throughout
The discs perform on all power outputs, although high-powered angle grinders will achieve optimal results. They are available in 4.5" and 5" diameter with either a 7/8" plain arbor hole, or a 5/8-11 thread for threaded spindles, in grit sizes of 40, 60, and 80. The 5/8-11 thread quick-change version has a zinc hub.
