This tapered Urethane Cutting Pad was developed for use with dual-action polishers such as Bigfoot’s and is optimal for initial cutting. Due to its hard, porous structure, it can withstand warping due to polisher vibration. Its rough foam makes it breathable and excellent at preventing heating. It also moderately stores polishing compound to make polishing more efficient. Suitable for use with RUPES Zephir compound.
