FlapwheelMaterial: The pressure used in grinding and finishing with a flap wheel does not justify ceramic or zirconia grain as no increase in performance would be seen. As such nearly all Flap wheels are X-weight aluminum oxide cotton cloth. Exceptions to this would be J weight cloth for increased flexibility and silicon carbide for special applications such as aerospace. Aeronautical engineers do not use recommend AO products due the high iron content in the mineral. If used on aero part the iron could contaminate the metal and become the source for crack to propagate under high stress conditions. Mounted Flap Wheels are available with a or ¼ straight shank or a ¼-20 male threaded shank. The shank is used in the mold and die industry for precision work with MFW in the diameter range 3/8 to 1 3/16. ¼ straight shank and a ¼-20 threaded shanks are the most common shanks for general usage.
