The Germans were the first to use the term “karot” and invented the core drilling machine to take samples from concrete through research. With this machine, they were able to drill concrete in a cylinder shape, extract the concrete that remained inside the cylinder and resembled a carrot. This method was named “karot” from the German word for carrot, “Karotte”. Thus, the process of drilling concrete in a cylinder shape became known as “karot” and those who perform this process using core drilling machines are called “karotçu” in Turkish.
In construction, concrete drilling and cutting work is called coring. Coring involves drilling into concrete to remove cylindrical samples or cutting concrete into desired shapes and sizes without damaging the surrounding area using a variety of cutting machines. The cutting machines have been developed to be used in both horizontal and vertical positions and can meet various cutting needs. The process is performed with minimal vibration and slippage, and the resulting blocks can be removed with the reinforcement bars still intact.
It is a technology that allows for quick and trouble-free operation in repair works to be carried out in all kinds of reinforced concrete buildings with or without iron, such as heating installations, dirty/clean water, chimney holes, door/window, air conditioning, elevator/stairwell openings, natural gas installation holes, and similar.
