PFERD INC. says its latest depressed-center grinding wheels feature an advanced ceramic oxide grain that delivers excellent stock-removal rates, long service life and cost-cutting performance. Ideally suited for working with steel and stainless steel, the new wheels, designated CO 24 Q SG, have a hardness grade Q and excel at a variety of applications, including weld grinding, chamfering, deburring and grinding wheel in a plane parallel to the grinding wheel spindle.

The grinding wheels achieve optimal results on high-powered angle grinders, and are available in sizes ranging from 4.5 in. dia. x ¼-in. thickness and a maximum rpm of 13,300 to 9 in. dia. x ¼-in. thickness and a maximum rpm of 6,600.

The ceramic-oxide grinding wheel employs contamination-free abrasives without fillers and is rated for stainless steel (INOX).
