Patent ID: 8764517

Claim:
An abrasive article comprising: a mounting assembly comprising an elongated body having a first end having a shaft for attachment to a rotary tool, a second end having an aperture, at least one sidewall extending between the first end and the second end, an elongated cavity extending from the aperture toward the first end having a central axis, and a first interlock member comprising a threaded portion proximate the second end and wherein the sidewall comprises a threaded portion and a non-threaded portion; and an abrasive attachment assembly comprising an abrasive layer attachment interface having a second interlock member comprising a threaded portion proximate the abrasive layer attachment interface and a non-threaded portion extending from the threaded portion, an abrasive layer affixed to the abrasive layer attachment interface, and a channel that extends through the second interlock member and the abrasive layer, the abrasive attachment assembly having a central axis; wherein the first interlock member and the second interlock member are configured to align the central axis of the abrasive attachment assembly and the central axis of the mounting assembly, and the first interlock member releasably engages the second interlock member; and the non-threaded portion of the mounting assembly releasably engages with the non-threaded portion of the second interlock member; and wherein when the first interlock member engages with the second interlock member to create an assembled wheel hub cleaning tool, a bore is formed having a length from a working surface of the abrasive layer to an end of the elongated cavity, the length being sufficient to allow the working surface of the abrasive layer to clean an area of a wheel hub proximate a threaded stud projecting from the wheel hub when the threaded stud resides in the bore.
