The tool is intended for cutting, brushing, and roughing metal, stone, plastic, and composite materials, as well as drilling in stone with diamond core cutters without water.
Safety
Always wear personal protective equipment, including safety goggles. Ensure the protective guard is correctly mounted and adjusted to minimize exposure to the operator. Do not use the tool for polishing. Always check abrasive tools for damage before use; perform a test run for at least one minute without load.
