drill bit
Chuck's rotating cutter
A drill bit is the detachable cutting tool that fits into a drill, doing the actual work of boring holes.
Bits come in various sizes and shapes for different materials—wood, metal, masonry, concrete.
The spiral grooves along the shaft carry debris out of the hole as you drill.
I need a masonry bit for this concrete wall.
