Features and Benefits

• Combines powerful penetration with agility and easy operation.
• Integrated drilling system is comprised of all-hydraulic controls and a reactive damper control system, which work together to accommodate changing rock conditions. The hydraulic controls automatically adjust impact and feed force, while the damper control system regulates pressure based on rock hardness.
• Dual damper system maximizes energy transfer to produce straighter holes.
• Compact valve design provides rapid valve and piston response for enhanced performance.
• Quick Extraction Device (Q.E.D.) allows easy removal of stuck rods.

Easy to maintain accumulators
feature long-life diaphragms.

Rugged, dirt-resistant in-line shuttle valve requires little maintenance.

New variable-stroke piston is designed to maximise energy transmission, delivering maximum drill performance in a variety of rock types.

Unique dual-damper system provides straighter holes and increased drill tool life.

Internally lubricated fronthead means no oiler to fill and no bearings to grease.
