The HP Plus is a synthetic, once piece (solid) constructed polishing wheel used to increase absorbency and maximize polishing action. Special construction techniques align the fibers into an optimum position to increase absorbency. This fiber orientation facilitates quick and thorough "wetting" to ensure high-performance polishing even with low polish flow rates. The HP Plus is treated with a proprietary polishing enhancer to allow it to polish at lower pressures extending wheel life and minimizing spindle wear.
