102 x 16mm Zirconium P40 Flap Disc.
Zirconium flap discs are longer wearing than aluminium oxide and are especially good on stainless steel, however can also be used to good effect on mild steel. Used with a standard angle grinder they do not require a backing pad and can be used in place of a standard sanding disc. Due to the overlapping layered design the life of the flap disc is greatly enhanced when compared to the traditional sanding disc and have replaced them in many sectors and applications.
