Provided are buffing pads that have intertwined seams such that any hard or unyielding edges are covered and not exposed during a buffing or polishing process. A double-sided buffing pad for polishing surfaces comprises a backing plate; two fibrous buffing media with filaments of textiles extending therefrom that are affixed one media to each face of the backing plate; and a seam that is intertwined by a portion of the filaments from each media are intertwined. The filaments may be intertwined by needle-tacking, air entanglement, or hydro-entanglement.

An abrasive rotary tool includes a tool shank defining an axis of rotation for the rotary tool, and an abrasive external working surface. The abrasive external working surface includes a resin, and a plurality of porous ceramic abrasive composites dispersed in the resin, the porous ceramic abrasive composites including individual abrasive particles dispersed in a porous ceramic matrix. At least a portion of the porous ceramic matrix comprises glassy ceramic material. A ratio of the average porous ceramic abrasive composite size to the average individual abrasive particle size is no greater than 15 to 1.

An abrasive rotary tool includes a tool shank a flexible planar section positioned opposite the tool shank. The flexible planar section forms a first abrasive external surface on a first side of the flexible planar section and a second abrasive external surface on a second side of the flexible planar section. The flexible planar section facilitates abrading, corners of a workpiece across multiple angles relative to the axis of rotation for the rotary tool through bending of the flexible planar section when the abrasive external surfaces are applied to a corner of the workpiece.

The present disclosure relates to abrasive buffing articles (abrasive buffs) and methods of making the same. The abrasive buffs include a substrate, such as a fabric, that has been impregnated with an abrasive polymeric composition that includes abrasive particles, such as primary abrasive particles and/or abrasive aggregates, such as spray dried abrasive aggregates. The abrasive buffs are flexible and capable of conforming to and effectively abrading, polishing, and buffing workpieces possessing a complex geometry.

A lapping device is provided that is capable of precisely lapping a surface of an object having a complicated shape, the lapping device including a driving unit, a shank connected to the driving unit through a driving shaft, and a lapping portion coupled to the shank. The lapping portion includes an abrasive layer and an elastic member between the abrasive layer and the shank.

A self-contained fibrous buffing article comprising at least one layer of a fibrous nonwoven fabric comprising lyocell fiber and having a hardened adherent coating comprising a crosslinked binder, abrasive particles, and a lubricant.
