An abrasive article comprising a first group including a plurality of shaped abrasive particles overlying a backing, wherein the plurality of shaped abrasive particles of the first group defines a first non-shadowing distribution relative to each other.

A bonded abrasive wheel is disclosed comprising a plurality of abrasive particles disposed in a binder, a first grinding surface, a second surface opposing the first grinding surface, and an outer circumference. The wheel comprises a rotational axis extending through a central hub and a circuit configured as a Radio Frequency Identification (RFID) unit coupled to the abrasive wheel. The circuit comprises an antenna configured to communicate with one or more external devices and comprising a first end and a second end, wherein antenna has a radius of curvature about an axis along at least a portion thereof such that the first end is disposed adjacent to but is spaced from the second end, and an integrated circuit (IC) operably coupled to the antenna and configured to store at least a first data.

A fixed abrasive article having a body including abrasive particles contained within a bond material, the abrasive particles including shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, each of the shaped abrasive particles or elongated abrasive particles having a predetermined position or a predetermined three-axis orientation, including a placement angle ranging from +90 degrees to −90 degrees and a rake angle ranging from +90 degrees to −90 degrees.

An abrasive article comprising a first group including a plurality of shaped abrasive particles overlying a backing, wherein the plurality of shaped abrasive particles of the first group define a first non-shadowing distribution relative to each other.

A roughing disc for machining material surfaces, which may have a disc-shaped main body having a tool side, which can face a tool, and a workpiece side, which can face a workpiece, the main body having a central opening through which an axis of rotation passes and which serves for direct or indirect attachment of a drive shaft of the tool, a disc-shaped backing layer disposed on the tool side, at least one abrasive layer, and a separating layer between adjacent layers. The backing layer may be made of a material mixture that is free of abrasive additives and that has at least one mineral additive.

The present disclosure relates to an abrasive article with a cork backing layer. In addition, the present disclosure relates to a method for producing abrasive articles comprising a cork backing layer.

An abrasive article comprising a first group including a plurality of shaped abrasive particles overlying a backing, wherein the plurality of shaped abrasive particles of the first group define a first non-shadowing distribution relative to each other.

A sanding tool system including a sanding plate with a metal composition having a first layer composed of a corrosive inhibitor and a second layer composed of an abrasive material. The sanding plate also has one or more evacuation ports extending through the metal composition, one or more recesses extending partially into at least the second layer of the metal composition, a retaining lip extending around a perimeter of the metal composition, and a connector attached to the first layer. The system additionally includes a sanding tool removably attached to the sanding plate via the connector.
