1.Threaded Button Bits Button bit, face design: Flat face, Drop centre, Normal and Retrac body; Tungsten carbide buttons: spherical, ballistic and conical. (Threaded R22 R25 R28 R32 T38 T45 T51 GT60; bit diameter: 32mm-152mm). 2.Thread Extension Steel Bars for Rock Drilling Our thread drill rod mainly include MF rod, extension rod, drifer rod, shank end adapter rod, own high fatigue strength, elasticity, rigidity and toughness, but strength and toughness is contradictory. The thread at both ends of the thread rods is a whole set of drilling tools, it's the key part of rod. It is well known that the performance of the material could be played well only after going through heat treatment to release its maximum potential, therefore, the choice of material and heat treatment process are important on an equal basis. 3.Couplings Sleeves Jixing’s rock drilling coupling sleeves are manufactured with a middle stop to prevent walking along the thread. Include couplings sleeve (Threaded T45, T51 T38,R22, R25, R28, R32, R38, ). 4.Shank Adapters R32, R38, T38, T45, T51 thread rock drilling shank adaptors are carburized and manufactured with tight tolerances and controlled straightness, which are suitable for all popular drifters and top hammers in the world, such as Atlas Copco series drifters, Tamrock series drifters, Garden Dever series drifters etc.
