Diamond core drilling is a common technique that's used in making flawless, round-shaped holes in concrete structures, floors and walls. Safety is of utmost important when handling core drills and diamond drill bits as they can be dangerous and cause damage when used incorrectly. Here you will learn some safety tips that you should have in mind before embarking on your drilling project.
Inspect the site
Before starting your drilling project or marking the holes to be drilled, you should carry out a thorough inspection of the site. Since most diamond core drilling projects involve drilling through concrete, the chances are that you will be doing it on an already existing structure. The structure may have utility lines, such as plumbing pipes and electrical wiring, and stress cables embedded in the concrete. Failure to account for the location of these conduits and wires may lead you to hit them when drilling. This can cause safety concerns, especially if you hit electrical wiring or ruin your structures' systems.
Make sure that there are no pipes and wires underneath the concrete you want to work on before starting the project. You can obtain the structure's blueprints or use Ground Penetrating Radar (GPR) to have a clear view of obstructions underneath the concrete.
Set up the equipment correctly
Setting up the drilling equipment correctly is not only essential for your safety, but it can also reduce downtime during the project. The core drill motor should not be loose on the drill stand as it can alter the drilling angle and cause the diamond drill bits to jam in the concrete. Secure the motor to the drill stand so that it doesn't move during operation.
Set the drill rig so that it is at a perpendicular angle to the concrete surface. You can do this by adjusting the screws that are located on each corner of the drill base. This will prevent the drill bits form jamming in the concrete and slowing down the work.
Wear protective clothing
Personal safety is essential when undertaking any drilling work. As such, ensure that you have the right clothing for the job. Avoid loose clothing which can easily tangle in the drill motor and cause accidents. Also, wear protective glasses, especially if you are undertaking dry drilling. Some earplugs or earmuffs can also come in handy to protect your hearing. When the noise is too loud, the nerve endings in the inner ear are affected, and this can reduce your hearing ability with time.
Observe these safety tips when handling core drilling equipment. Ask a professional core drilling contractor for help if you have any problem setting up or using the core drill.
