The bristles are made of stainless steel and have a twisted wire shape, making them tougher and more durable for better cleaning. Our 1/4" hex handle is easier to use than a screw handle. You can mount the Stainless Steel Bore Brush to the appropriate driver handle or to a drill or die grinder for more efficient cleaning. Stainless steel bore brushes can make your cleaning job extremely convenient. Designed for easy access to narrow holes and confined areas, wire cleaning bore brushes are widely used for dusting, descaling, de-etching and polishing pipes, ports and bearings. Please note that these stainless steel bore brushes should only be used in a push-pull action. When using an electric drill or die grinder, avoid rotating counterclockwise and do not exceed 600 rpm.
