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.


“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


Calculate your annual savings



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.


Percussion of RD1840C is optimized for large hole drilling. High impact energy together with optimal pulse form gives perfect drilling performance and long rock tool service life.

  • High nominal drilling power with optimal stroke dynamics.
  • State-of-the-art manufacturing.
  • Well tested and robust structure.
  • Service interval 500 h.
  • RockPulse™ option available.




Our LT90 rock tools are developed to perfectly match the drill rig Pantera™ DP1600i and the rock drill RD1840C. The tool system, manufactured in Sweden, offers the best possible drilling dynamics and rock breaking efficiency. The patented optimized design increases your productivity, improves the hole straightness, provides great coupling characteristics and longer tool service life. All in all a much better drilling experience.

How can top hammer XL reduce your climate impact?

Higher speed and penetration rate

The top hammer drilling method used in the Top Hammer XL system can give you significantly increased drilling speed and penetration rate compared to DTH-methods on the market.

50% less fuel consumption

With the new Top Hammer XL system, you can save up to 50% fuel due to the inherently more fuel-efficient top hammer drilling method and more productive drilling.

Radically reduced CO2 emissions

50% less fuel consumption gives you a significant reduction in CO2 emissions , making your business more sustainable. With the Top Hammer XL system you could reduce your C02 emissions by more than 530 000 kg per year which is equal to the annual CO2 emissions of 170 family cars.

Reducing the environmental footprint is a must in our industry to fight climate change.

The story of the Top Hammer XL system


Optimizing drilling operations and cutting costs is a constant focus of surface mining companies. Sandvik now has a powerfull solution for this: Top Hammer XL. This new concept expands the hole size range of the top hammer drliing up to 178 millimeters (7"). The Top Hammer XL system makes your drilling procedure duel efficient and challanges the DTH drilling with the opportunity to drill much larger scale holes than before.
