Hammer drills work like standard drills but include a hammering function that drives the bit into the material while the bit turns. This impact helps the bit get through tough materials like concrete, brick, and block with much more ease on the bit and the user than a standard drill. Hammer drills come in both corded and cordless models. Corded drills generally offer more power and higher drilling speed (measured in rotations per minute, or RPM), and they don't slow down with use like cordless drills do as their batteries wear down. Cordless drills offer convenience and tend to feel and operate more like standard drills.
At a special virtual product launch event, Drilltech International Mining and Rock Solutions introduced the Top Hammer Drill Rigs, its latest innovation in surface Top Hammer Drilling.
The new, groundbreaking drilling system, targeting large-scale quarry and surface mining customers, offers a faster, more fuel-efficient and more cost-effective way to drill holes 140 to 178 mm (5.5 to 7 in.) in diameter.
The components of the system, a new Pantera DP1600i drill rig, new RD1840C rock drill and new LT90 rock tools – are all optimized to work together seamlessly for exceptional drilling results. It is part of Drill Tech International commitment to use engineering and innovation to make the shift that will drive safer and more sustainable business. In addition to excellent drilling results, it offers an effective solution to reduce fuel consumption and, ultimately, CO2 emissions.
This more fuel-efficient yet productive drilling method can help Drill Tech International customers grow their business in a more sustainable way, the company stated.
The new RD1840C rock drill is designed for large hole drilling with high 49-kW (66-hp) drilling power. Its robust design and well-balanced long piston percussion package are made especially for demanding circumstances. The new layout of pressure accumulators maximizes efficiency and minimizes hose vibrations. The state-of-the-art manufacturing process ensures the required high quality of the rock drill components.
The long piston technology generates high-impact energy with optimum pulse form, optimizing performance in large hole drilling without compromising the rock tools’ service life. The geometry and physical dimensions of the new RD1840C rock drill have been optimized for the entire Top Hammer Drill Rigs.
As an additional option, RD1840C will be available with the Drill Tech International RockPulse tool stress monitoring system later in 2021. The system offers the drill operator real-time measurement data on three key drilling parameters: Drill Bit Response, Tools Load and Feed Level. The system measures the stress waves and guides the operator to find the right drilling parameters for the best rock contact and performance.
“A key asset of the Top Hammer Drill Rigs is that all three main components, the drill rig, rock drill and rock tools have been reviewed, redesigned and mutually optimized,” said Jukka Siltanen, product line manager, rock drills at Drilltech International Mining and Rock Solutions.
The efficiency of the new Top Hammer Drill Rigs system stems from the three components. The proven carrier offers a solid base for the extremely powerful rock drill that generates an optimum pulse for the effective tooling system, which in turn transfers the high-energy shock wave with minimum losses to the rock.
The Top Hammer Drill Rigs system has been thoroughly tested and proven in several field tests by drilling more than 100,000 meters in challenging rock conditions. The test results in the given conditions show a 50% reduction in fuel consumption, 25% reduction in total drilling costs and 15% increase in productivity compared with the DTH drilling method.
