Horizontal Boring Tool

The Grundomat piercing tool from TT Technologies is ideal for water and sewer service and lateral installations. Sixteen models, from 1.75 inches to 7 inches (44 mm to 178 mm) in diameter, are available for horizontal boring distances from 50 ft to 150 ft (15 m to 46 m). The Grundomat offers high-impact power and is easily reversed during the bore. The tool's reciprocating stepped-cone chisel head helps ensure accuracy in rocky soils.
