The STEEL type is the most universal bond for machining steel and cast steel. It is ideal for grinding high-speed steel (HSS) molded parts and weld dressing on steel constructions. Series A mounted points are generally used on larger components. Due to the special shapes of series A mounted points, it is possible to grind in a variety of contours. Applications include grinding out slits and grooves in hard-to-reach areas, machining bores and small holes, and smoothing surfaces.
