What Is a Pneumatic Piercing Tool?

A pneumatic piercing tool, also called a pneumatic mole, is an air compressor-powered tool that pushes through the soil to make a horizontal bore. It lets crews run cable, conduit, and pipe under driveways, sidewalks, and roads without an open trench.
Contractors use many names for this tool, including mole, pneumatic hole hog, and boring missile. They all describe a tool that makes a trenchless bore with soil displacement.
