Concrete core drilling is a non-percussive process that uses a specialised drill bit to cut a solid, round hole through a concrete slab. It is a great choice for creating openings for electrical, plumbing and air-conditioner piping and conduit through concrete walls and floors. Unlike traditional jackhammers, it minimises structural damage to surrounding areas. It also reduces harmful concrete dust by flushing out the cuts with water.
Getting the most out of your core drill means making sure that you plan correctly for the size of the hole you are trying to make. For this, you should use a template or mark out the area with chalk. This will ensure that you get the right hole size and that it is in the correct location.
Breaking Ground: The Basics of Concrete Core Drilling
Once you have the hole planned, it is time to select a drill bit. For this, you should choose a diamond-tipped drill bit that has been specially designed for concrete and is in good condition. This will make sure that your concrete cutting is as smooth and precise as possible.
For the best results, you should apply a moderate amount of pressure to the drill bit during the core drilling process. Too little pressure can cause the diamonds on your bit to glaze over, while too much can overload your drill motor and create unnecessary stress.
