A grinder is a power tool used for grinding, sharpening, or polishing materials like metal, wood, or stone. It works by using a rotating abrasive wheel or disc that grinds away small amounts of material from the surface.

A grinder is a kitchen tool or appliance used for breaking down or reducing solid substances into smaller, more manageable pieces or powders. Grinders typically consist of a grinding mechanism, such as blades or burrs within a container or casing. They can be manual or electric, with electric models powered by motors to automate the grinding process. Grinders are commonly used for grinding coffee beans into grounds for brewing coffee, spices into powder for seasoning dishes, or grains into flour for baking. They come in various types and sizes, from handheld spice grinders to countertop coffee grinders or larger industrial-grade mills.
