Concrete core drilling is a dusty affair, especially if you are drilling indoors without the right protective gear, which exposes you to lung-damaging silica. It is for this reason that wet core drilling is recommended since it dampens a drilling site, thus reducing dust levels significantly. However, you can only benefit from wet core drilling if you know what is required of you. Regrettably, most workers do not follow correct wet core drilling techniques, and they end up with low quality work. Nonetheless, if you are starting to use wet core drilling equipment, then this article highlights ideas to ensure excellent results. 

Start Drilling at an Angle -- Before you start drilling a concrete surface, you must drill a pilot hole, and this is achieved by drilling at an angle. Some workers forget this part and hold the core drill perpendicularly from the onset. Since you will be using water during the drilling process, vertical drilling activity increases the chances of the core drill sliding off the concrete surface. By beginning the drilling action at an angle, you create a notch for the core drill to settle, thereby making the equipment easier to work with as you flood the spot with water. Notably, a pilot hole eliminates chances of the core drill bit skidding or moving laterally, which can lead to accidents.

Maintain Constant Water Flow -- During wet core drilling, there are instances when the work area feels flooded. Notably, you might be tempted to stop the water flow, even if for a few minutes. If you do that, then it is highly likely that the drilling equipment will heat up. Most importantly, however, stopping the flow of water increases binding in the hole and also wears the core drill fast. A better approach is to reduce the amount of water flowing through the equipment instead of turning it off altogether. If you don't have a sufficient supply of water, then you can use a core drilling machine that is equipped with a water management system. Instead of letting used water to go to waste, wet core drilling equipment with a water management system recycles the water for repeated cycles.

Don't Dry Remove Core Drill -- Once core drilling is complete, it is common for workers to turn off the water and the equipment motor before pulling the core bit from its hole. However, it is a wrong approach because turning off the water makes it challenging to pull the drill from the hole. It is even harder to do so with the motor switched off because the core drill loses its mechanical advantage. A better approach is to turn the water down low then pull the drill with the motor still running as it helps prevent possible damage to the drill bit.
