However in certain case such as preparation of soft material, Silicon Carbide has greater removal rate & as it is resin bonded , can be used with a lubricant , which prevents overshooting of the sample, minimizes shearing of soft metals & also provides a rising action to flush away surface removal product so the paper will not be clogged.
