KLINGSPOR wire wheels perform well in a variety of applications. These fit most 4-1/2" - 5" angle grinders and are perfect for general clean-up of rust and scale, weld spatter and weld seams. These can be used in your shop and around the home. Crimped Wire Cup Brushes are designed for light to medium-duty brushing applications on flat or irregular surfaces, and bevel buffing. Standard Twisted Knot Wheels are ideal for removing weld scale spatter, extra-heavy rust and corrosion, or surface roughening. Twisted Cup Knot Wheels are designed for high impact cutting and cleaning on more demanding applications.
