Used with drill on low speed, this handy tool provides equal pressure on the inner hub bore, polishing to minimize imperfections and flaws inside the wheel bore. The result is a reduction in break-in time and a faster racer! The Pro-Bore Polisher cleans and polishes the wheel bore to minimize friction. In addition to the Pro-Bore Polisher, a pipe cleaner (supplied), 1 micron plastic polish, a hand drill, and a clamp are required.
