RD1840C Rock drill

RD1840C rock drill is designed for large hole drilling of Ø 140…178 mm (5½”…7”) holes with high 49 kW drilling power. Its robust design and well-balanced long piston percussion package are made especially for demanding circumstances. The long piston technology generates high-impact energy with optimum pulse form. This provides perfect drilling performance in large hole drilling without compromising the rock tools’ service life. The geometry and physical dimensions of the RD1840C rock drill have been optimized for the Top Hammer XL drilling system.

As an additional option, RD1840C will be available with the Sandvik RockPulse™ tool stress monitoring system. 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.
