Final answer:
A detail grinder uses abrasive compounds to polish metal, as they provide a smooth finish without leaving debris.
Step-by-step explanation:
A detail grinder uses abrasive compounds to smooth and polish intricate metallic work. Abrasive compounds are usually made from materials like pumice, calcium carbonate (limestone, chalk, dolomite), kaolinite, quartz, soapstone, or talc. These substances are effective polishing agents that allow detail grinders to achieve a high level of smoothness and shine without leaving behind the type of tiny flakes or debris that materials such as coarse sandpaper might leave.
