boring machines

Earth-penetrating excavators

Boring machines are industrial tools that enlarge or finish holes in metal, wood, or other materials.

Unlike drills, which create holes, boring machines refine existing holes to precise diameters: The boring machine achieved tolerances within a thousandth of an inch.

Tunnel boring machines are massive devices that excavate underground passages for subways, sewers, and mines.
