Industrial drilling and boring jobs require the very best equipment that is reliable and performs at peak efficiency. As with all tools and machinery, there are different types of drill for different jobs.

Large drills are used to perform tasks that could, of course, never be done by a common hand one. They are used for a wide variety of jobs such as scientific explorations of the earth (both dry and underwater), as a means to get to natural resources such as petroleum and natural gas, and digging water wells. For mining and tunneling operations, drills are essential for making holes to hold blasting charges.

Before the advent of pneumatic devices, 19th century miners had to use a whole lot of muscle power to do their drilling: two men were needed for the operation; one would turn a long thick drill bit in a nearly continuous motion while his partner drove it deeper with hammer swings. Needless to say, the process was extremely arduous and slow.

Today, drills come in three types: percussive, rotary, and rotary-percussive. Which kind is used depends on the type and hardness of earth or rock being worked on. Percussive drills use the hard shock of impact to chip away at resistant materials. As its name implies, a rotary one turns and simply grinds the material out of the way. The rotary-percussive can switch back and forth between functions depending on what kind of resistance it encounters.

Industrial rotary drills look most like the commonly used home tools, particularly the earth auger. It has a spiral-shaped attachment which can easily work its way through soft earth. As the hole deepens, the worker simply adds on sections to the main body and keeps drilling away till the job is finished.

Other rotary bits are more appropriate for harder boring work, and must be tipped with appropriate materials to both accomplish the job and resist the stress of the friction. Tungsten carbide helps to drill through soft rock and diamond bits have the ability to grind through very hard rock.

Today's industrial drills come in a variety of sizes to adapt to whatever they're being used to do. Huge devices can be mounted on rigs in order to bore multiple holes at once. Smaller versions of these tools are more convenient for mining operations in confined spaces. Whatever size you choose, you're sure to perform any industrial job more quickly, more efficiently, and much more safely than at any other time in history.
