Abstract

An abrasive wheel, in particular an abrasive cutting-off wheel, comprises an annular cylindrical inner support of metal and an abrasive ring surrounding the latter, both being connected with each other. The abrasive ring projects on both sides from the support in the direction of the common axis. The abrasive ring can be ground off completely. The support is re-usable or at least recyclable.
