3M Fibre Disc 501C consists of sharp aluminium zirconium mineral on a fibre backing, making this product ideal for removing welds and for other applications requiring medium-high pressure (e.g. deburring or rust removal). Aluminium zirconium is a material that allows you to grind quickly and obtain a consistent finish on mild steel. You also get good results on stainless steel with this material.
Characteristics:
Aluminium zirconium forms a consistently sharp edge when breaking down, which cuts faster than aluminium oxide and is therefore suitable for material removal on all metals, including stainless steel.
Rigid fibre backing provides the durability needed to remove welds and other applications requiring medium pressure, such as deburring or rust removal.
Durable resin adhesive resists heat, extends disc life and provides excellent mineral retention when grinding edges.
