Advanced Systems Designed to Drill Faster and Straighter
The HD 700 Series drifter with dual dampening system (DDS) provides the ultimate combination of performance and economy. Designed to minimize noise and vibration without sacrificing performance, the HD700 series maximizes energy transmission and drills effectively in a variety of rock types.
The HD 822 drifter (patent applied for) provides greater penetration with increased impact. With 20% more impact than its predecessor, the HD 822 performs in harder rock and drills larger diameters. Designed around DDS, drilling adjusts automatically for maximum performance regardless of rock.
