There are many types of bits classified and used according to the purpose of drilling or ground conditions, and the bits are also different in their material, shape, and performance.So, it is economical and highly effective in drilling works to use the proper bits after full understanding of the characteristics of each bit. Diamond Core Bit is used for the drilling of hard rocks, and Metal Bit is normally used for the ground or soft rocks. Impregnated Core Bit is normally used in case Core is needed, while Non Core Bit is used if Core is not needed.However the drilling efficiency and economic feasibility increase if Core Bit is used while Core is not needed. Features of Impregnated Diamond Core Bits of Taesung Reached up to the global quality level. In Korea, rocks are generally very strong. Bits of Taesung Co. have an excellent drilling rate. at strong rocks as they have been adapted to such hard and strong rocks. Firmly positioned as a leading company in domestic market. Bits can be diversely produced in any sizes and specifications that are needed. Drilling Speed of the Impregnated Core Bit is very excellent comparing with those of other companies. Premium product that Synthetic Diamond Powder, Metal Powder, and Shank of top quality are used. The hardness of Matrix is the most important factor in selecting bits. Large size diamond with the strong matrix is used for soft rocks. Medium size diamond with the matrix of medium strength is used for the rocks of medium strength. Small size diamond with soft matrix is used for strong rocks.
