A damped abrasive article comprises a damping body and an abrasive surface provided on at least a portion of the damping body. The damping body comprises a synthetic polymer having a Storage Modulus from 1000 MPa to 2500 MPa and a Loss factor from 0.025 to 0.10 at 25 C. and 10 Hz.

An example trimming tool includes a floating base having a first side and an opposite, second side, a first rail, and a second rail. At least the second side of the floating base, the first rail and the second rail define a workspace having a first opening and a second opening. The trimming tool also includes a milling apparatus, attached to the floating base, having a base on the first side of the floating base and a milling head on the second side of the floating base. The milling head is spring loaded. The floating base and milling apparatus are configured to remove at least a portion of a foam layer in the workspace.

A grinding device has a support unit attached to a rotary shaft so as to be rotatable integrally with the rotary shaft, and a grinding element stacked on the support unit and having an uneven grinding surface formed by a plurality of abrasive grains. The support unit has, in a surface thereof, protruding surface portions to be brought into contact with a rear surface of the grinding element when in use, and recessed surface portions recessed from the protruding surface portions, alternately located in a circumferential direction. An engagement mechanism which makes an engagement at each of predetermined angular positions so as to retain the grinding element or the support unit moved by a predetermined angle in the circumferential direction, is provided between the support unit and the grinding element, between the rotary shaft and the grinding element, or between the rotary shaft and the support unit.

An abrasive finishing article with an adapter or hub to attach to an appropriate power tool, wherein the hub contains sets of slots to receive ribs positioned on a grinding wheel to permit adjustment of the height of the hub to change the overall height of the grinding wheel and abrasive finishing article.

A grinding body including a substantially cylindrical outer member for receiving an abrasive material, an inner member for attaching the grinding body to a drive unit, and a connecting structure for mechanical force transmission between the outer member and the inner member. The outer member, the inner member, and/or the connecting structure may be made at least in part of a fiber-plastic composite.

A holding device, in particular a grinding disc, for a grinding member includes at least one support member that has at least one material opening configured for transverse transport of grinding dust to one side facing the grinding member in a plane parallel to a grinding surface. The holding device further includes at least one securing layer configured to secure the grinding member on the at least one support member. When decoupled from the grinding member, the at least one material opening is at least substantially open on a side facing the grinding member and on a side facing away from the grinding member is substantially delimited by the support member.
