For cutting only. Do not use for grinding. Always wear proper eye, face, hand, hearing, and body protection. Use only with compatible tools, guards, and operating speeds, and confirm the tool speed does not exceed the maximum RPM marked on the wheel. Inspect each wheel before use; never use a cracked, dropped, or damaged wheel. Follow the tool manufacturer's instructions and ANSI B7.1 abrasive wheel safety practices.
