    Product Description

    TT Technologies GRUNDOMAT Piercing Tool Basic Packages -

    Grundomat Pneumatic Piercing Tools have been the trusted choice for accurate horizontal boring beneath roads, railways, and landscaping projects worldwide for nearly 45 years. Widely used in the water, gas, sewer, and electrical industries, this trenchless technology workhorse requires minimal operating space and often serves as a cost-effective alternative to larger, more expensive directional drilling equipment.

    The GRUNDOMAT® Basic Package Includes:

    • Grundomat Boring Tool
    • 50′ Air Supply Hose
    • In-line Lubricator
    • Magnetic Starting Level
    • Operators & Parts Manual
    • 1 Gallon Grundo-Oil® Tool Lubricant

    Piercing Tool Capabilities

    The Grundomat Horizontal Boring Tool can perform precise horizontal bores ranging from 50 to 150 feet. It is suitable for all displaceable soils—including sand, loam, and even gravel—and can be configured to pull in a wide variety of new pipe materials.

    Superior Accuracy Compared to Conventional Piercing Tools

    Unlike fixed-head piercing tools that follow the path of least resistance and are easily deflected by obstacles, the Grundomat’s patented reciprocating stepped-cone chisel head hammers directly through difficult soils and solid obstructions. This unique two-stroke action focuses the piston’s impact on the tool head, delivering consistent accuracy and superior trenchless boring performance.

    Key Features of the Grundomat:

    • Easy Reverse Function: 5"–7" diameter models include a patented reverse mechanism, allowing reversal during the bore by adjusting a lever on the lubricator—no hose turning required.
    • Quick Setup: Can be launched by hand or from a cradle with minimal setup time.
    • Durable Construction: Built for long-lasting use with low maintenance.
    • Patented Stepped-Cone Chisel Head: Provides powerful, accurate boring action.

    Benefits of Trenchless Technology:

    • Greater accuracy than conventional pneumatic boring tools
    • Bore and pipe pull-in performed in one step
    • Minimal disruption to traffic, buildings, and nearby utilities
    • Avoids costly surface damage and restoration from trenching methods
    • Faster project completion with smaller crew requirements
    • Simple to set up and operate
