| Claim:
This invention relates to improvements in a hard cutting material useful as an abrasive in bonded grinding Wheels, or as an efficient lapping compound, but whose chief use at the present would seem to be a tool material for use in high speed machining of hardened material, or the machining of highly abrasive materials such as carbon or cast iron. |
