One of the most versatile and useful methods of cutting through concrete is core hole drilling. Core drills can drill deep, they can drill wide and they can cut almost any irregular shape into concrete, steel or stone. However, one of the unique aspects of core drilling is that they run almost silently creating little to no disturbance to surrounding structures.
Cutting concrete uses various tools to shape and removed hardened concrete. There are a variety of concrete saws from hand-held, to wire and road saws. There are grinders, sanders and polishers. And, the third is core drills. Core drills are more or less the same in process with the width or length of drill bit being variable.
Core drilling comes into it’s own in the following ways
Depth of cut
Most core drills can drill as deep as 700mm (70cm). Specialised core drills can drill much deeper. This is much deeper than a concrete saw can cut. For very thick concrete slabs concrete drilling is usually the chosen method. By drilling successive holes together, a process known as stitch drilling, thick concrete can be cut in any shape imaginable.
Trueness of cut
A core drill cuts a perfectly round hole in one setup. Holes up to the width of a manhole are commonly cut with holes larger than this certainly possible. A core drill is mounted once and can drill away quietly until the hole has been cut. Fitting pipes, windows and any other cylindrical object is made easier with core drilling as the size of the hole can be determined precisely.
A core drill is known as a non-percussive process. This means there is minimal vibration caused by the drilling process. This causes minimal disturbance to surrounding areas and minimises any related structural damage that could occur using other methods jsuch as jackhammers. Water is also applied to the cutting surface for cooling purposes and also to suppress harmful concrete dust.
Core drilling is a very useful form of concrete cutting with many applications. If you ever need a true, deep or perfectly round hole cut into a concrete slab it is your best option.
