The Brush Research BRM-BC23418 Flex-Hone is a 2-3/4" diameter, 180-grit flexible honing tool engineered for engine cylinder finishing. Its flexible synthetic abrasive globules conform to the bore contours, effectively removing light scratches, surface imperfections, and burrs while producing an ideal crosshatch finish for proper oil retention and ring seating.
Built for durability and consistent performance, this tool is ideal for automotive, marine, and small-engine applications where precise bore surface preparation is critical. The self-centering, self-aligning design makes it easy to use with a standard electric drill, delivering professional results in the shop or garage.
