RH drills are designed for heavier jobs such as bench and secondary drilling, plus drilling for smooth blasting.
RH drills have a robust rifle-bar rotation mechanism and high impact energy for drilling hard rock.
The Right Drill for Your Application
The light-weight RH571 is perfect for smaller jobs. The RH 568, slightly heavier and more powerful is suitable for greater hole depths. The RH 572E combines light weight with extra operator comport, thanks to the vibration dampened handles and efficient silencer.
All models are equipped with T-handles for a solid, comfortable grip.
