A Brief Look at Rock Drilling Equipment

Tuesday, April 5, 2016

Drilling through rock is no easy job, and it calls for special equipment. Rock drills have special features such as lubrication, cooling systems and extra hard bits. Often the drills come equipped with air blowers to blow out debris reducing stress and damage to the special bits. The drills are attached to rigs, or controlled manually by an operator. At WORD Rock Drills we recommend protective eye, face and ear gear when near an active drill.

Jobs and Drills

The type of rock drilling equipment needed varies according to the surface and the specific application of any given job. Rock drills tackle anchoring, blasting, fencing and mining jobs to name just a few, and the type of job dictates the equipment needed for the job. A simple example is using a rock drill for fencing. At WORD Rock Drills depending on job specifics we recommend a hydraulic rock drill with a rotary head with air, water and mud flushing.

Drilling Systems

To continue on with our fencing example, you may want to consider a drifter system. Drifter systems are hydraulic or pneumatic with rotary heads. The drills we recommend at WORD Rock Drills are all hydraulic, and the MO15, MO37, MO57, M125 Hydraulic Rotary Head models are especially lightweight and easy to handle with torque equal to heavier rock drilling equipment. They all offer air, water and mud flushing and are all suitable for fencing jobs. For large holes the MO57 and M125 are recommended.


It's important to the note the flushing systems. As the drill penetrates, debris builds up and can damage the bit or drill, so flushing reduces the critical stress upon the bit and drill. Flushing removes the debris, but special care must be taken to ensure the gap between the hole wall and the rod is neither too large or too narrow to avoid clogging. Air and water flushing are the most common means of flushing out debris, but the choice of a flushing system depends on the type of rock and materials that need to be drilled. The type of rock drilling equipment used and the different types of systems available depends on the individual jobs and experience of the crew, but the most important factor in drilling any type of rock is the safety practices you employ.
