High - Performance Rock Drills for Mining & Tunneling

A number of different factors need to be taken into account when selecting a rock drill; however, the most crucial are the type of the rock formation and its hardness. Less durable rocks can be drilled with less powerful drills, whereas tougher rocks require more robust models to be drilled easily. Another factor that needs to be accounted for is the power source; pneumatic drills are easy to carry around and good for a variety of applications, while hydraulic models are much more powerful but suited to demanding applications. The weight and size of the drill are equally important, especially for handheld models, as they determine the operator's fatigue when used over long periods of time. Consider also the requirements in depth and diameter for the hole to drilled. The versatility of the drill can be further improved by purchasing optional accessories and attachments, such as different drill bits. Last, but certainly not least, the reputation of the manufacturer and the presence of after-sales service should be taken into account.
