straight flute
Noun: A straight flute is a type of rock drill bit. Its defining characteristic is that its cutting edges or grooves (called flutes) run in a straight line parallel to the axis of the drill, rather than being twisted or spiral. This design is used for specific drilling applications in masonry or rock.
