Frequently Asked Questions

Which shank types is the Bestlink 6 inch DTH hammer compatible with?

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.

Can this DTH hammer be used for water well drilling?

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.

What air pressure does the DHD360-type hammer require?

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.

How do I order a compatible DTH button bit with this hammer?

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.
