La única desventaja que les encuentro es que por estar fabricadas con dióxido de aluminio son muy abrasivas. Al menos para mi, que soy aficionado a la carpintería. Desafortunadamente no encuentro bandas de lija de dióxido de silicio. Entonces uso primero estas lijas de banda en grano 400 en mis maderas, y luego mi lijadora orbital en granos más finos y con lijas de óxido de silicio.
