the tool that doesn't make holes, it perfects the ones already there
means A rotating cutting tool used to enlarge, smooth, or precisely size an existing hole to exact dimensions.
from From the verb 'ream,' meaning to widen or clear out an opening, which traces back to Old English 'ryman,' to make room or enlarge — a relative of 'room' itself. The tool name simply attaches the agent suffix '-er,' so a reamer is literally 'a thing that makes more room.'
