Zusammenfassung:PROBLEM TO BE SOLVED: To prevent a disc from hitting on an obstacle, and to facilitate a removal of swarf upon an operation, in an abrasive system comprising a fiber-backed abrasive disc and a backup pad. SOLUTION: An abrasive system comprises a backup pad 12 and, supported thereon in face to face relationship, a fiber-backed abrasive disc 1, wherein the backup pad has a maximum radius that is from 95 to 100% of the maximum radius of the abrasive disc and a circumference from which, at spaced intervals, from three to six segments have been removed such that, in the area of the removed segments, the abrasive disc overlaps the backup pad by an amount that is from 10 to 20% of the maximum radius of the abrasive disc.
