Terracore tungsten carbide bits are designed especially for overburden drilling and soft soil sampling coal, lime stone and clay. The bits are extremely cost-effective in the correct application. The tungsten carbide bits can be used for clean-out operations, such as for the removal of steel fragments from a hole. Corborit bits have considerably more cutting edges than standard TC bits, and are recommended in medium to medium-hard sedimentary formations. Corborit bits cause less vibration, offering better core recovery than standard TC bits.
