Rock Drill Dry

This air flushed medium duty rock drill machine and rock drills is capable of drilling 27-48 mm diameter holes with H22 integral steel upto a depth of 6 meters. Rock Drills can be used for holes upto 20 feet or over but are most efficient when confined to holes of not over 10 to 12 feet. Hydraulic Rock Drills, Rock Drill Machine And Rock Drills (Dry) has following applications:

• Built-in air-flushing gives faster blasting cycles
• Stepless throttle for easy collaring
• Robust tick-latch retainer – changes steels quickly and easily.
• Silencer in impact and wear-resistant polyurethane reduces noise levels by more than 50%.

Pressed for time? Work often behind schedule? Then take a look at HAVA rock drills. Customers have told us that high productivity is make or break; so we've built in features that help you get the job done faster.

Built-in air-flushing
Take the built-in air-flushing for example. As you drill, the hole is kept clean by a powerful jet of air. This boosts productivity in two ways. First, it speeds up the actual drilling process, since the drill bit has a cleaner surface to work on. Two, when the drilling is finished, you don't need to clean the hole before blasting.

Easier collaring
We've also made collaring faster and easier. HAVA drills are powerful, but the power is easy to handle thanks to a stepless throttle. This helps you keep the tip of the tool exactly where you want it, right from the beginning.
