| Construction industry is greatly developed these days. Lots of buildings and other structures are erected daily throughout the world. Construction business does not stay still, it is permanently developing. New techniques and methods applied in building activity are created and successfully used. Among such methods is so-called core drilling presenting the process of quiet and non-percussive drilling with the objective to produce precise holes. Absolutely round holes are created with special core drills specifically designed to remove the cylinder of material without dust. The material left inside the drill bit is referred to as the core. That is where the term core drilling originates from. With the help of such drills you have an exclusive chance to make holes of various sizes and deepness.
Core drilling technique is applied in various fields of industry, such as mechanisms, water systems, telecommunication line fitting, heating, gas supply, railway and bridges building and so forth. Core drills are also frequently used in mining for assessment of core samples by geologists. As a consequence of such examination exploration companies take a decision whether there is sense in proceeding with mineral exploration in this particular area or not.
There are also different power processes in core drills, like electric, pneumatic and hydraulic ones. Electric one is the most widespread option used in creating holes in concrete, tile, gravestones, granite and other similar materials. It's also suitable for home repair and making holes in ceilings, walls, floors etc. Hydraulic option are usually used with the objective of creating holes of larger diameter. Pneumatic option is also utilized to walls, ceilings, floors and other concrete structures. It's based on the utilization of a diamond core drilling technique.
So, at present time core drilling method is the best invented method to make smooth holes with minimal noise and complete absence of dust. It is a true achievement in construction industry. |
