Hydraulic Rock Drills with External Flushing Head

Atlas Copco has released two new versions of its COP 1838 hydraulic rock drill—the COP 1838MUX and COP 1838HUX—intended for use in underground long-hole drilling. The new versions feature an external flushing head combined with the extractor unit to improve serviceability; this is now standard on all Atlas Copco top hammer rock drills that have an extractor unit. An upgrade kit with external flushing head will be available for older versions. The external flushing head provides improved serviceability when changing flush seals because the extractor unit does not have to be removed—so there is no need to retorque the side bolts afterward and fewer tools are needed for drill operation. The head also reduces the risk of water intrusion on the rock drill which should increase the life of essential components.
