Concrete core drilling is the process of drilling
perfectly round holes through concrete walls, floors and other concrete
structures. Concrete core drilling is the most commonly recognized use of any
diamond concrete cutting tool. Concrete core drills or "core rigs"
can be operated in any orientation, vertical, horizontal and even upside down
through concrete ceilings. A concrete core drill bit consists of a steel tube
with diamond segments brazed or laser welded on the drilling end. The core bits
are mounted on the rotating shaft of various types of concrete core drilling Brisbane
machines.
Generally speaking,
core drilling is done so that it will be easier for materials involved with the
home utilities like electricity, healing and plumbing. The holes drilled are
usually useful in installing vault taps and manhole taps. Even computer lines,
phone lines and water pipes may need concrete core drilling Brisbane services.
Windows and doors may
also be drilled into concrete walls and surfaces using concrete core drilling Brisbane services.
Most concrete core drills are connected to a stand
that is secured to a wall or floor with a concrete anchor and a bolt but there
are also concrete core drills that use vacuum pressure to attach to a floor.
There are also many different types of hand held core drills. Concrete core
drills can be powered by electricity, hydraulic, gasoline or air power sources.
Core holes are used for utility penetrations such as electrical, plumbing and
heating but are also commonly used for venting furnaces or clothes dryers.
Concrete core drilling also allows concrete structures to easily be made ready
for sprinkler systems, HVAC ducts, fiber optics, phone lines, computer lines
and much more. Concrete core
drilling methods are used widely in underground utilities
construction, most commonly, manhole taps, underground vault taps, and wherever
sewer, water, steam, air or communication lines pass through a concrete or
brick structure.
A core drill machine meant for concrete is used to
drill larger holes. Reading recommendation from the manufacturer is really
necessary to make the use of the machine to its best. In addition to this, it
is always recommended to wear protective equipments for hassle-free operation.
Therefore, never avoid reading recommendations to ensure complete safety and to
get maximum of your effort.
Line drilling or line coring is similar to perforating, when core holes are
drilled in a series of overlapping holes in a row, allowing for one large piece
of concrete to be removed. Line coring is an effective method for cutting and
removing small, square or rectangle openings of almost any thickness of
concrete where other concrete sawing or cutting methods cannot be applied.
Although not recommended, concrete core drilling can be performed by an
advanced do it yourselfer and the equipment necessary to perform concrete core
drilling is readily available at your local tool rental and supply store. Most
professional concrete cutting companies have a minimum charge of $250 to core a
hole for you and it can take a professional as little as 10 minutes to unload
his equipment, core the hole, and reload his equipment. Yet, I have seen
homeowners rent the equipment and spend an entire weekend trying to core a
single hole and then call a professional concrete cutter in to complete the
project anyways. Just like with any trade a professional concrete cutter will
make his job look easy.
