• Hardness grade O-tools are ideally suited for heavy-duty edge grinding on steels, they are noted for their high edge-holding and dimensional stability, long service life and low wear
• Due to their special edge-holding properties, hardness grade O-mounted points can also be used economically with low Rpm power tools
