Top hammer XL: Expand the limit open up a world of possibilities
Sandvik’s latest innovation is proof that a seemingly marginal difference can make a significant change. The new, fully optimized drilling system consists of Pantera™ DP1600i drill rig, RD1840C rock drill and LT90 rock tools. It expands the limits for top hammer drilling, allowing you to drill blast holes from 140 to 178 mm (5½ to 7") with the top hammer drilling method. At the same time, you achieve faster, more fuel-efficient and more cost-effective drilling, with considerable savings in time, money, and CO2 emissions.
THE FUTURE IN TOP HAMMER DRILLING
“A key asset of the Top Hammer XL concept is that all three main components of the drilling system – the rig, the rock drill and the rock tools – have been reviewed, redesigned and mutually optimized. It truly works very well as a whole.” Jukka Siltanen, Product Manager, BU Rock Drills at Sandvik
TOP HAMMER XL
Pantera™ DP1600i is the newest member of the Pantera DPi series family of intelligent top hammer drill rigs. It is characterized by high penetration rates and advanced automation options for data-based fleet management and drilling performance optimization. It fits perfectly for production drilling in large quarries or open pit mines.

INNOVATED TO INCREASE YOUR PRODUCTIVITY
Top Hammer XL is designed and innovated to maximize the power of your drilling.
HOW DOES IT WORK?
- Long piston technology provides high impact energy with optimal pulse form
- The length of the pulse depends on the length of the piston
- Rock drill and tools are dimensioned to work together, which offers the best possible drilling dynamics and rock breaking efficiency.
