Cobalt–tungsten carbide hard metals have properties of extreme hardness, abrasion resistance, and toughness and are used primarily in cutting tools and ... and grinding of tools. Historically, exposure levels from production have decreased over time, possibly as a result of improved industrial hygiene in hard-metal producing factories.
Cobalt Steel and the Grinding Wheel. Before I mess up my stone, I thought a quick post here may be extremely prudent. I have an older SuperGrind 2000 (Square cabinet, no serial number). The stone is not marked with a part number. The label says "SuperGrind" and it is the light grey stone. I would believe it is the original stone to the tool.
