Drilling all the way through the surface of the Earth is no small task and can only be done with the right equipment. Among these tools is the DIC-Impregnate Core Bit, an essential device in the process of drilling. Gaseous core bits are a necessary tool in underground rock and sediment sampling for geological examinations.
Gas core drill bits offer some unique benefits that make them the vibrator of choice for geological exploration. Unlike the solid core bit method of the past, which involves hard rock breaking up and accumulating at its center, gas core bits create an open tube in which to collect samples. This makes it easier for samples to be removed and lowers the possibility of sample breakage.
Gas core bits also increase drilling efficiency and accuracy. With gas as a hydraulic transport medium, the drilling cuttings can be rapidly eliminated from the space which leads to obstruction-free storage and a reduction in the degree of difficulty as far as drilling sensation is concerned. This helps the drillers to save time and effort as sample is obtained accurately.
There are several main components of gas core bits that cooperate to achieve efficient sampling. The entire bit is studded with a diamond-impregnated crown at the end of the bit that cuts rock and sediment. The hollow body is used for collecting the samples and for their transportation to the surface. The gas evacuation system assists in removal cutting from the drilling zone, under high G forces, so as to keep the bit clean and operational.
The more correctly gas core bits are used and maintained, the longer their service life and efficiency. The regular checking of wear of the AC crown, replacement of the tube when needed and cleaning of the gas flushing system are important factors. Furthermore, drilling properly and utilizing the correct drilling speed and pressure can prevent damage to the bit and extract a sample correctly.
