The invention proceeds from a grinding-means device, in particular from a grinding-disc device or from a backup-pad device, for arranging at least one grinding means, in particular at least one grinding wheel, on a portable power tool (14), in particular a grinding machine, having at least one receiving unit (18), in particular a grinding disc or backup pad, which is fixable in particular in a thread-free manner on an output unit (16) of the portable power tool (14) and on which at least one grinding means is able to be arranged, and having at least one securing unit (20), formed in particular separately from the receiving unit (18), at least for axially fixing the receiving unit (18) and/or the grinding means to the output unit (16) of the portable power tool (14). It is proposed that the securing unit (20) be provided at least to axially fix the receiving unit (18) and/or the grinding means to the output unit (16) of the portable power tool (14) in a tool-free manner, and/or at least to axially fix the grinding means to the receiving unit (18) in a tool-free manner.
