It's made from tough, non-woven fibres and an aluminium-oxide abrasive to provide a tough, durable surface-conditioning disc. This component offers a high cut-rate, impressive strength and low heat retention for an effective, long-lasting solution. The plastic threaded screw can be quickly swapped out with other Roloc discs for fast and convenient use. • Medium grade offers flexibility and versatility so this disc can be used in a range of applications• Convenient pack includes 50 discs • Maximum safe speed of 23,000 RPM offers powerful capacity• P50 grit size indicates a coarse abrasive that's able to remove materials quickly Applications • Aircraft manufacture and maintenance• Construction industry• Shipbuilding and marine operations The unique construction of the Scotch-Brite™ disc is made up of non-woven fibres and aluminium oxide abrasive making it tough and durable. Compared to traditional abrasives that quickly wear down when used, this discs high cut-rate, hardness, strength and low heat retention make aluminium oxide a popular choice. What's a non-woven disc? A non-woven disc is made of short and long fibres that are bonded chemically, thermally or mechanically rather than by weaving. Once coated with aluminium-oxide abrasive, non-woven fibres are extremely strong. Quick Change system The Roloc™ system from 3M™ provides a secure attachment on heavy duty applications.
