ABSTRACT:
The invention describes an abrasive system comprising a fiber-backed abrasive disc and a backup pad in which the backup pad has spaced portions removed from the circumference such that the disc overlaps in the area of the removed portions. This has the effect of inhibiting catching of the disc on obstructions and enabling easy swarf removal during operation.
