The Bestlink 6 inch DTH hammer is compatible with DHD360, SD6, QL60, M60 and Cop66 shank standards, covering hole diameters from 152 mm to 203 mm with API 3 1/2" Reg connection.
Yes. The valveless air distribution design makes it reliable for water well drilling, as well as mining, quarrying, geothermal and construction drilling in hard rock or overburden formations.
It is a high air pressure hammer. For best penetration rates, pair it with a compressor delivering 17-24 bar working pressure; lower pressure reduces impact energy and drilling speed.
Match the bit shank to the hammer standard (DHD360/SD6/QL60/M60/Cop66) and specify hole diameter and rock hardness. Bestlink, a Xiamen-based manufacturer since 1985, supplies matched hammer-and-bit sets with OEM support.
