Sandvik DT920i is a computer-controlled two-boom electro-hydraulic drilling jumbo for tunneling and cavern excavation of 12-125 sq. m (129 - 1345 sq. ft) cross sections, including face drilling, bolt hole drilling, and mechanized long-hole drilling.

The Sandvik DTi jumbos are designed with successful operations in mind: They are fast, accurate and user-friendly. Together with the iSURE tunnel management program, their intelligent control system, high frequency HFX5T rock drills, robust booms and advanced drill string guides offer an excavation result of the highest quality, with the lowest costs.

The DTi design focuses on ease of service. The components are damage-protected, and all daily service points are accessible from the ground level.
