Diamond Coring Diamond Coring is a technique in the mining industry for the extraction of core samples. It is suitable for geotechnical projects in both cemented rock as well as hard rock environments. Diamond coring down pressure and fluid circulation are carefully examined during the drilling process. We offer a wide range of drill bits depending upon the type of rock and core size.
Diamond core drilling is best suited for the extraction of solid core samples from deep and hard rock environments. It works best in tough conditions. It is accustomed to auger and rotary sonic drill rigs that enable it to penetrate deep into the surface and overcome all sorts of limitations offered by the site.
