Patented tapered shape with several advantages over traditional glass fibre backed products. 5% tapered shape, facilitates the use of the abrasive crown, allowing the entire surface area of the abrasive to be used. More material available, as the inside hole of the abrasive crown is only 22mm against 50/55mm of fibre backed products. Nylon backing does not damage the surface,as a fibre backed product does, in case of contact with the workpiece.
