TOP HAMMER ROCK DRILLING TOOLS
These drills transfer vibrational force to the drill rods that is in turn transferred to the drill bit. The vibration can be actuated up to 5000 times per minute with a rotational speed of up to 200 spins per minute. The combination of these actions allows holes to be drilled into hard rock and materials excess are usually flushed from the base of the hole with water under high pressure. These tools are used in the construction, mining and quarry sectors often in combination with blasting for an very efficient and effective means of excavation.
