Normally rock drill button bits' body is made of high quality imported special steel 45CrNiMoV, the cutting head is made of special alloy YK05 after special processing. (Atlas Copco Button Bit - China Button Bits, Retrac Button Bit, Threaded Button Bits Suppliers, Spherical Button Bits, T45 Button Bits) Jinquan's tungsten carbide buttons are with superior wear resistance and impact toughness superior, with higher drilling speed compared with the similar rock drilling tools. Rock button drill bits series tools’ passivation time is longer, approximate 5-6 times of the other drill bits. This is beneficial to save the auxiliary working hours, reduce manual labor and accelerate the construction speed. Our rock drilling bits are widely used in all kinds of mining, drilling, quarrying, engineering, construction, water well drilling, oil exploring etc. Main threaded button bits are: R22-32mm, R22-36mm, R22-38mm, R22-41mm; R25-33mm, R25-35mm, R25-37mm, R25-38mm, R25-41mm, R25-43mm, R25-45mm; R28-37mm, R28-38mm, R28-41mm, R28-43mm, R28-45mm, R28-48mm; R32-41mm, R32-43mm, R32-45mm, R32-48mm, R32-51mm, R32-54mm, R32-57mm, R32-64mm, R32-76mm; T38-64mm, T38-70mm, T38-76mm, T38-89mm, T38-102mm, T38-127mm; T45-76mm, T45-89mm, T45-102mm; T51-89mm, T51-102mm, T51-115mm , T51-127mm; T60-92mm, T60-96mm, T60-102mm, T60-115mm, T60-118mm, T60-127mm, T60-140mm, T60-152mm etc. R22 R25 R28 R32 T38 T45 T51 T60 threaded button bits could be produced as per your requirements completely, such as flat face or drop-center face; normal body or retrac body; spherical buttons, ballistic buttons or parabolic buttons.
