Weiler Corp. offers an assortment of high-performance wire brushes designed specifically for use on 4-1/2-inch right-angle grinders.
The 4-1/2-inch Mini Roughneck stringer bead wheel features a high knot count and short trim length to produce fast, effective cleaning action and long product life. Dually 4-1/2-inch weld cleaning brushes feature a dual-hex nut design to simplify periodic flipping of the wheel in demanding inter-pass weld cleaning applications. Standard 4-inch twist-knot-wire bevel brushes feature a tufted knot end and a saucer-shape design that is said to provide an aggressive-yet-flexible brushing action for cleaning filet welds and into corners. The company’s 3-1/2-inch knot-wire and crimped-wire cup brushes are suited for cleaning large surfaces.
According to the company, the larger sizes of these brushes offer increased cleaning action over more-common 4-inch stringer bead wheels or 2-3/4-inch cup brushes. Their heavier-duty construction also is said to offer increased aggression and prolonged life.
