Weiler 3" Stem-Mounted Crimped Wire Radial Wheel provides a flexible brushing action and consistent performance for demanding light-duty cleaning and deburring applications on steel. Side plates for a shorter trim length and more controlled brushing action. The permanently-attached 1/4 in stem are primarily intended for use on high speed die grinders. Although they can also be mounted onto a drill, the speed and power of that tool will decrease effectiveness of the brush. Featuring Weiler's solid ring construction, these radial wheels are available in heat-treated steel, type 302 stainless steel and brass wire.
