8 1/2" is the most regular sizes in rock drilling fields, including water well drilling, oil well drilling, geothermal well drilling, HDD horizontal drilling, foundation piling, etc. Thirds (1/3) of 8 1/2" tricone bits is widely used in building HDD hole openers and foundation piling core barrel and drill bucket. Far Eastern are factory specializes in drill bits,such as tricone bits, PDC bits, HDD hole opener,Foundation roller cutters for different applications. As a leading drill bits factory in China,increase the drill bit working life is our target. We always try to improve the bits with high penetration rates.Our mission is lower the cost of drilling-per-meter. Far eastern drilling's quality and technology will help you to achieve more!
