Bits Cutting And Application
These bits are characterized by moderately spaced conical inserts with medium projection. This configuration promotes good penetration rates in medium hard and moderately abrasive formations. Smaller carbide inserts are provided on the gage and inner rows or hard metal is deposited in the nose area to contain shell erosion and improve
Tricone drill bit is the best all-purpose drill bit and can be used for many different types of rock formations, such as Soft Rock Formations (consist mainly of sand, clay, limestone or shale), Medium Rock Formations (calcites, dolomites, hard limestones, and some hard shale), Hard and Abrasive Formation (hard shale, calcites, mudstones, chert, pyrite, granite, quartzite, and cherty lime stones).
