Finishing Stone Polishes Variety of Surfaces

The Rasp from Boride Engineered Abrasives is an all-around finishing stone made from select premium aluminum oxide grain and designed to improve cut and finish on tool steels, aluminum and EDM surfaces. The polishing stone, which can be used by hand or in a profiler, is formulated with a proprietary lubricant that enables it to be used wet or dry. It is suited for flat lapping and is said to contour quickly with a moderate breakdown.
