Abrasive brush

Abstract

This invention provides an abrasive brush having strength and abrasive characteristics similar or superior to those of conventional brushes, and which allows a brush assembly having a desired width dimension and a desired brush surface hardness to be readily and easily assembled. A disk-shaped abrasive brush 1 includes a radial inner hub 5 and a radial outer brush section 3, preferably the hub 5 being integrally formed with the brush section 3. The hub 5 is provided with a flat part, a recessed part 9, 11, and a projecting part 7. When two adjacent abrasive brushes are aligned adjacent to each other, the flat, recessed and projecting parts of the abrasive brushes are engaged with each other and define a pitch between the abrasive brushes.
