chignole -> drill

Une chignole ou perceuse est un outil utilisé pour faire des trous dans des matériaux divers : ciment, bois, métaux. Elle peut être manuelle ou électrique. Le mot « chignole » fait référence à la version manuelle, celui de « perceuse » désigne plutôt la version électrique. Son nom vient du latin ciconia : cigogne.

A drill or drill motor is a tool fitted with a rotating cutting tool, usually a drill bit, used for drilling holes in various materials. The cutting tool is gripped by a chuck at one end of the drill and rotated while pressed against the target material. The tip of the cutting tool does the work of cutting into the target material. This may be slicing off thin shavings (twist drills or auger bits), grinding off small particles (oil drilling), crushing and removing pieces of the workpiece (SDS masonry drill), countersinking, counterboring, or other operations.

A tool for cutting or enlarging holes in hard materials. There are two classes of drills: those that have a rotary action, with a cutting edge or edges at the point and, usually, helical fluting along the shank; and those that work by percussive action, where repeated blows drive the drill into the material.
