DTH Hammerbit

According to the different geological conditions and rock-hardness of the customers to produce the flat, convex and concave bits. According to the different parts of the PDC, it can be divided into two main points: 1. All-PDC tooth: All tooth use diamond enhanced composite insert to replace the carbide, which makes the bit has high efficiency and useful life, and the useful life is 50 times up more than ordinary bits. 2. Around-PDC tooth: The tooth around the bit use diamond enhanced composite insert to replace the carbide, and other parts still use carbide tooth. Compared with the bit all with carbide tooth, it has high cost performance, and its useful life is 20 times up more than ordinary bits.
