PFERD Grade O mounted points consist of pink Aluminum Oxide grain in a vitrified bond. Features good edge holding and long service life, making it predominant in applications like deburring of steel castings, chamfering, and contour and edge refining on forgings. Ideally suited for heavy-duty edge grinding on steels. PFERD Grade O points are noted for dimensional stability and long service life, and can be used economically with lower RPM tools.
