Construction industry is greatly developed at present time. Lots of buildings and other facilities are erected every day throughout the world. Construction business doesn't stay still, it is permanently developing. New techniques and methods used in building activity are created and successfully used. One of such techniques is so called core drilling presenting the process of quiet and smooth drilling with the objective to make precise holes. Absolutely round holes are made with specialized core drills specially designed to remove the cylinder of material without dust. The material inside the drill bit is referred to as the core. That is where the name core drilling originates from. With the help of these drills you have an exclusive opportunity to produce holes of various sizes and deepness.
Core drilling technique is used in different branches of industry, including mechanisms, telecommunication line fitting, water systems, gas supply, heating, bridge and railway building and so on. Core drills are also frequently used in mineral exploration for assessment of core samples by geologists. After this examination exploration companies decide whether there is sense in proceeding with mineral exploration in this area or not.
There are also different power processes in core drills, such as electric, pneumatic and hydraulic ones. Electric process is the most popular option used in creating holes in tile, concrete, gravestones, granite and other similar materials. It is also appropriate for home repair and making holes in walls, ceilings, floors etc. Hydraulic process are usually applied with the objective of creating holes of larger diameter. Pneumatic process is also applied to walls, ceilings, floors and similar concrete structures. It is founded on the use of a diamond core drilling.
In conclusion, at the present time core drilling technique is the best invented method to make round holes with minimum noise and complete absence of dust. It is a true achievement in construction industry. |
