    Abstract: The present disclosure provides abrasive articles that include an abrasive layer having a contact surface, a first layer coupled to the abrasive layer, and a second layer coupled to the first layer. The first layer is configured to provide contact pressure to the abrasive layer, such as through a higher hardness than the second layer. The second layer is configured to provide conformability to the abrasive layer, such as through a higher compressibility than the first layer. The resulting abrasive articles may exert a consistent contact pressure against a substrate with increased conformability around the substrate, reduced hysteresis, improved removal rate consistency, and/or improved lifetime over abrasive articles that do not use the multiple layer construction described above.

    IPC: B24D5/02

    Abstract: The disclosure is generally directed to a method of manufacturing an abrasive rotary tool using a molded elastic layer. A mold includes a cavity with a peripheral surface. An abrasive sheet is positioned so that a working surface of the abrasive sheet is positioned along at least a portion of the peripheral surface. A spindle is positioned within the mold to create a region between the spindle and the abrasive sheet. An elastomeric precursor material is injected into the region and solidified to form an elastic layer. As a result, the elastic layer is in direct contact with at least a portion of the opposed surface of the abrasive sheet and at least a portion of the exterior surface of the spindle. In this way, an abrasive rotary tool may be manufactured without using adhesive layers and/or fastening means.

    Abstract: The disclosure provides abrasive rotary tools with enhanced adhesion of an abrasive layer. Exemplary abrasive rotary tools include a securing element configured to secure an abrasive layer to an abrasive rotary tool. The securing element may be positioned over a portion of the abrasive layer, such as a tab or end, such that repeated forces on the abrasive layer do not decouple the abrasive layer from the rotary tool. In this way, an abrasive rotary tool may maintain a contact surface integrity through repeated use for extended life of the rotary tool.
