Rock drills are specialized devices used for drilling into hard substrates like rock. They have hard bits made of industrial diamonds and require special training to operate. They can be rented or purchased, and come in different sizes and models for various applications. Safety features like emergency stops and cages are standard.
A rock drill is a drilling device designed specifically to penetrate rock, for use in tasks such as well-drilling, foundation preparation, and mineral exploration. A number of companies manufacture rock drills, often offering a range of different models to suit different needs. This equipment tends to be expensive and requires special training to use it. Drillers can be rented and operators can be hired by companies that do not have a full-time need for a rock drill and operator.
Drilling in rock is a challenge because the substrate is very hard. Ordinary drills can be damaged quickly. Rock drills feature particularly hard bits made from materials such as industrial diamonds, along with lubrication and cooling systems to limit the stress caused by friction. The drill can also use an air blower to clear the drill hole as the drill penetrates, limiting damage to the drill caused by rock dust and other particulate materials.
Rock drills can be attached to drilling rigs for jobs when very deep drilling is required. They can also be operated manually by an operator, in the form of a pneumatic rock drill with an accelerator. In either case, people should wear appropriate eye, ear, and face protection when working around the drill. These drills are loud and inhaling the rock dust or getting it into your eyes can be very uncomfortable. Drill crews and personnel in the area typically wear face shields and ear plugs to limit injuries associated with their jobs.
With rock drills for purchase, people may be able to rent or test out different models before making a purchasing decision. Drilling needs vary widely and because this equipment is expensive, companies usually want to make sure their customers are fully satisfied. In the case of rental drillers, people can pay by the hour or day, depending on the job, and they can also hire an operator to run the rock drill or provide instructions to people at the job site so they can take over the operations of drilling.
Companies with different models on offer typically have a range of sizes, as well as drills intended for particular applications. A rock drill can be equipped to take core samples for mining exploration, for example. Safety features such as emergency stops, drills that automatically shut off when no one touches the throttle controls, and cages around the moving areas of the bit are usually installed on drills. While it is sometimes possible to override security features for specific applications, this is generally not recommended.
