The Cup Brush Crimp by Josco provides a medium to a heavy-duty crimping tool suited to remove paint and rust from your gutters. Twisted wire bevel brush removes paint and rust effectively from the gutter. Quickchange multi-thread allows for cleanliness through multiple jobs. Designed to work with M14 Drill Adaptor BDBPA for use in a drill, the Cup Brush is perfect for cleaning off rust or paint from surfaces and will fit in a standard drill chuck. The brush uses crimped steel wire bristles that will not fall out, allowing you to use the brush at an angle to the workpiece with extra pressure for stubborn rust or paint. Excessive pressure causes wire breakage. Not to be used on stainless steel or aluminium as it can cause rust contamination.
