Hard Rock TCI Drilling Bit insert hard tungsten carbid teeth . The hardness and wear resistance of the cemented carbide teeth are higher than that of the steel teeth, and the service life is longer than that of the steel teeth, especially for the hard layer with abrasiveness. It has a wide range of applicable strata, multiple footage, and many mechanical drilling speeds, and has been widely used in oil drilling.
The hard rock drill bit tooth profile of cemented carbide teeth is currently commonly used in more than ten kinds, such as spherical, pointed oval, conical, wedge, scoop, cone-shaped, top-shaped spoon, side wedge, flat head and so on. According to the different fracture modes of different strata and different lithologies, various drill bits use different shapes of teeth.
1. Rock drilling head specifications:
1. soft formations(417, 437, 517, 537)
features large chisel-shaped inserts to provide the highest penetration rate in the softest formations such as shales, clays, limestone and sands.
2. soft to medium formations(617, 637)
designed to drill effectively in formations such as hard limestone, dolomite, hard sands, and other formations with hard cherty.
3. medium to hard formations(737)
for extremely hard formations such as chert, granite, flint, and taconite. features short, closely spaced inserts to ensure maximum penetration rate and wear resistance.
