2,We are a professional company in supplying tri-cone bit, steel teeth bit, single cone bit, etc., bit sizes range from 3 7/8" to 26" and cover almost all IADC codes, and it can be used in several of different fields, mining, hydrology, subterranean heat piling, water well drilling and oil well drilling.
This type bits have optimal bearing design, it can be working stably in high WOB, and the quality tungsten carbide inserts on cone and gauge make a good wear resistance largely extend the working life of bit. It is suitable for medium to hard formation.
If you are interested in these products, you could send message to us, we will be glad to reply you soon
3,There are several factors that affect drill bit selection. Due to the high number of wells that have been drilled, using information from an adjacent well is most often used to make the appropriate selection. A major factor in drill bit selection is the type of formation that needs to be drilled. The effectiveness of a drill bit varies by formation type. There are three types of formations: soft, medium and hard. A soft formation includes unconsolidated sands, clays, soft limestone, red beds and shale. Medium formations include calcites, dolomites, limestone, and hard shale. Hard formations include hard shale, calcites, mudstones, cherty lime stones and hard and abrasive formations. Durability and rate of penetration are two key factors to clarify the bit quality.
We now can supply a full range of milled tooth and insert tooth rock bits size from 3 3/8" to 26".
