Introducing the TerraRox GT4 – the shortest and lightest tubeless 4″ DTH hammer on the market,
engineered for Nordic geothermal drilling.
Three reasons why the GT4 sets a new standard:
✦ No foot valve – the tubeless TD40 design eliminates one of the most common failure points in DTH drilling, reducing downtime and keeping you drilling
✦ Optimised piston geometry and premium materials deliver high, consistent penetration rate from the first metre to the last
✦ Specifically designed for the most commonly used compressors in the Nordics at 35 bar – maximum compatibility, no compromises
Less downtime. More metres.
