The present disclosure relates to a tool for sanding and buffing an irregularly shaped surface that includes a head having a rounded surface, a first abrasive material adapted for sanding or buffing, the first abrasive material attached to the rounded surface via an adhesive substance or other attaching means and at least partially covering the rounded surface, and a handle attached to the head. The tool may further include a second abrasive material attached to the rounded surface via the adhesive substance or other attaching means that at least partially covers a portion of the rounded surface not covered by the first abrasive material. If the first and second abrasive materials have varying properties such as their coarseness, the user may find each material to be especially efficient for use in separate sanding, buffing, or polishing processes.

An abrasive tool includes a tool base having a supporting surface and a generally cylindrical abrasive surface layer disposed on the supporting surface. The abrasive surface removes material from a work-piece outer surface by contact therewith and by relative movement along a defined working path. The abrasive tool comprises a first axially extending circumferential portion featuring an abrasive coating selected to produce a final finish on the work piece, and a second trailing portion that tapers radially inwardly to accommodate post-grind radial expansion of the work piece.

Methods of making thin abrasive cut-off wheels with low pinhole occurrence are disclosed. An abrasive cut-off wheel has a thickness of less than or equal to 1.6 millimeters. It comprises at least one reinforcing scrim and abrasive particles retained in a phenolic binder. The abrasive particles comprise first and second triangular abrasive platelets. The first triangular platelets have a first average maximum side length and a first total weight. The second triangular platelets have a second average maximum side length and a second total weight. The first and second total weights combined comprise at least 30 weight percent of the abrasive cut-off wheel. The ratio of the first average maximum side length to the second average maximum side length is 1.25:1 to 5:1, and the ratio of first total weight to the second total weight is 1:2 to 5:1.

A connector cleaner having an elongate portion of material extending from a first end portion to a second end portion; a first paddle element extending from the first end portion, and wherein at least a portion of a first side surface of the first paddle element includes an abrasive element or portion; a second paddle element extending from the first end portion, wherein at least a portion of a first side surface of the second paddle element includes an abrasive element or portion, and wherein the first side surface of the first paddle element is positioned adjacent the first side surface of the second paddle element; and a singular paddle element extending from the second end portion of the elongate portion of material, and wherein at least a portion of a first side surface of the singular paddle element includes an abrasive element or portion.

A roller assembly for a rotary dresser comprise a plurality of axial segments which may be in the form of discs, each disc provided with an abrasive, radially outer surface. The discs are secured in axial alignment, each in a preconfigured rotational orientation. The disc assembly has a centrally arranged aperture for receiving a rotor shaft. The abrasive surface of the assembly can be accurately presented as an array of uniformly shaped abrasive units in a predefined pattern.
