When installing a new tool, be sure to install the tool to see if it jumps. Must be adjusted to not jump to use. Otherwise the tool wears out quickly and the engraved object is not very smooth. 2. Be sure to cool the water when carving (like a dripper in a hospital). If dry drilled, the diamond in the tool head will be graphitized by overheating and will wear out quickly. The package contains: Diamond grinding head sheet set x 13. Note: 1. Due to manual measurement, please allow 1-2mm error, please don't mind. 2. Colors may vary slightly due to different monitors, please understand. 3. For long-term use, please use lubricant (water) when using tools.
