A new diamond drill bit with high efficiency and long life, was manufactured successfully after two years of research and development by Guilin Diamond Industrial Co., Ltd., which is double that of conventional bits in the aspect of service life and 30% higher than drilling efficiency of conventional bits. It has become the latest tool for deep ground engineering.

This bit makes new pre alloy powder used in diamond drill bit matrix, and produce new drill bit by using cold - hot pressing process, whose matrix strength is improved obviously, work layer more than 20 mm. After the successful research and development of new diamond bit, it was used in a drilling project in Yunnan, and the results showed that: In the VII-VIII (7 - 8) sandstone, the drilling efficiency is more than 3 meters/hour, the service life more than 400 meters, which are 1.3 times and 2 times of conventional diamond bits respectively; In VIII - IX (8-9) granite, the drilling efficiency is more than 1.5 meters/hour, the service life more than 150 meters, which are 1.2 times and 2 times that of conventional diamond bits respectively.

In deep drilling engineering, the drilling quality is the key factor affecting the drilling period and cost. The chief engineer of Guilin Diamond Industrial Co., Ltd., Zhou Tiansheng told us that new diamond bit can completely replace the similar imported products, and the price is higher than the imported drills, which is the latest tool for deep ground engineering. At present, the bit has been applied in deep drilling engineering in Yunnan, Sichuan and other provinces’ drilling companies.
