A drill bit is a tool used to create precise holes in various materials, like wood, metal, plastic, and concrete, by attaching it to a drill that spins the bit into the surface. Drill bits come in a range of shapes and designs, each tailored for specific jobs: some are general-purpose, while others are specialized for tougher materials like masonry or for creating large-diameter holes.
