Import Button Bits — Buy in Bulk from Supplier in China

Button bits are tungsten carbide-tipped drill bits used in rock drilling for mining, quarrying and construction. This range from Qingdao Stingray Rocktools is manufactured with grade T6 tungsten carbide inserts bonded to a high-grade steel body, designed to withstand high-impact drilling in hard rock formations. The bits are engineered to maintain sharpness and penetration rates over extended use in abrasive conditions.

The steel body is heat-treated to typical hardness values of 45-50 HRC for the shank and 55-60 HRC for the head, providing a balance of toughness and wear resistance. Standard button configurations include spherical, ballistic and conical profiles, with diameters typically ranging from 25mm to 48mm for common applications. The tungsten carbide grade T6 offers a typical density of 14.8 g/cm³ and a hardness of 1500-1600 HV, ensuring long service life in granite, basalt and similar hard rock.

These bits are used in down-the-hole (DTH) and top-hammer drilling rigs, with common applications in mineral exploration, tunnel construction and aggregate production. Buyers typically confirm compatibility with their rig’s chuck type and shank design (e.g., R25, R28, R32, R35 or hexagonal). Qingdao Stingray Rocktools offers flexible packaging options, with bits supplied in wooden cases or steel pallets to prevent damage during transit. Lead times and MOQs are confirmed directly with the supplier.
