Grundomat 95P (3 3/4 in.) (New)

The GRUNDOMAT 95 P is a 3 3/4 in. pneumatic piercing tool built for trenchless installation of pipes, cables, conduit, and utility lines. Powered by compressed air, this cylindrical air-hammer drives through the ground to create a clean underground bore without open-cut trenching.

What contractors use it for: boring under a driveway, sidewalk, road, or parking lot to install water service lines, electrical conduit, gas lines, irrigation and sprinkler lines, and fiber optic drops — no trench, no cut concrete, no landscaping repair. A typical residential driveway crossing takes minutes of boring time with a 53 CFM compressor.

Also known as: underground mole, boring missile, air mole, ground piercing tool, horizontal boring tool, trenchless bore tool, pneumatic gopher. Whatever your crew calls it — this is the 3 3/4 in. class tool.

As a pneumatic mole, the GRUNDOMAT 95 P performs well in displaceable soils such as sand, loam, and gravel, including soil conditions with fracturable rocks. It is not designed for solid rock or unfracturable rocks, and very soft soils may affect accuracy because the tool’s own weight can cause deviation.
