Case analysis
The following examples will show you how Goldstone uses its advanced manufacturing processes to improve drilling efficiency. The case comes from the real report of Tangshan Jinshi customer. Tangshan Jinshi HQ3 impregnated drill bit helps customers to realize efficient production. In April 2015, Tangshan Jinshi's HQ3 coring bit achieved good results with an average life of 800 meters under high-speed drilling. Detailed drilling environment is as follows: Construction party South Laos. The place is very remote. For drilling in this area, the transportation and replenishment of drilling materials often takes a lot of manpower, material resources and time. Therefore, the construction side more need to perform well cut durable products. Stratigraphic conditions
