Abrasive articles are disclosed comprising at least one primary elongate abrasive element extending along an element axis. The primary elongate abrasive element comprises a plurality of formed abrasive particles, wherein at least 50% of the formed abrasive particles are orientationally aligned along the element axis.

An abrasive article and method of making same wherein the abrasive article comprises a mounting assembly and an abrasive attachment assembly wherein the first interlock member of the mounting assembly and the second interlock member of the abrasive attachment assembly are configured to align the central axis of the abrasive attachment assembly and the central axis of the mounting assembly, and the first interlock member releasably engages the second interlock member. The abrasive article is adapted to clean a work surface area around studs using a rotary tool, including, for example, a drills or die grinder.

A convolute abrasive wheel formed from a spirally wound nonwoven abrasive web. The nonwoven abrasive web including a make coat and abrasive particles having a Vickers indentation hardness of at least 16 Gpa and a toughness of at least 3.0 Mpa m. A first size coat comprising a phenolic resin is applied over the make coat and the abrasive prepolymer is applied over the first size coat.

The Invention also provides the rotary tool having the article attached thereto and a method of using. The present invention relates to a cutting article having at least one rigid surface comprising a polymeric material designed for use with a rotary tool which is particularly useful for efficiently removing a material (such as a sealant, for example) from a substrate. Preferably the material is removed with minimal or no damage to the substrate.

Rigid polymeric cutting article, a rotary tool having the article attached thereto, and a method of using

A rotary surface treatment tool is attached to a rotational driver with a kit. The surface treatment tool includes a base with a middle portion around a center hole, and one or more attachment knobs are placed on the front side of the middle portion. An attachment plate or retainer nut has a flange which extends radially over the middle portion of the base. The attachment knobs mate with holes in the flange of the retainer nut. The surface treatment tool is tightened onto the shaft by turning the surface treatment tool, with the attachment knob turning the retainer nut and thereby tightening the retainer nut to the threaded shaft. Assembly and tightening without any tools is thus facilitated. The base may be made of a flexible, shape-retaining material, and recesses are provided behind the attachment knobs to permit use with a retainer nut without a mating recess. The surface treatment tool may be a brush having bristles which extend at about 90.degree. to the plane of the base. The bristles are disposed in a pattern of helical bristle curves, with each bristle curve providing a relatively continuous sweep.
