BD Drill supply Submicron or ultrafine tungsten carbide powder with grain size < 1µm. Used as material for semi finished POT and plunger; Used as material for tungsten carbide rods, tungsten carbide bars and other tungsten carbide products.

In order to meet the international upscale market demands for high grade cemented carbide on products of high-air pressure DTH bit, tricone bit and top hammer drill bit, Changsha Heijingang industrial co., Ltd (with brand name BD Drill) had established Cemented Carbide Section on December of 2015 based on the deep comprehending in drilling working conditions and acknowledges of bit manufacturing and TCI configurations. BD Drill has specialized in researching and manufacturing super strength and toughness cemented carbide of geologic and mining tools. The following is a brief introduction of the advantages of our cemented carbide.

TOP HAMMER BD DRILL supplies a top hammer line that covers all construction, quarrying and mining drill and blast applications, from the softest to the hardest of rock conditions. Drifting and tunneling bits Reaming equipment Rods, shanks and couplings.

Thread button drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized thread button drill.

RC Hammer and bits are widely used for exploration drilling.

Black Diamond produce a full range of reverse circulation down the hole hammers and bits, to suit all depths and ground conditions. Due to its high-quality sample results, and speed of operation for shallower holes, reverse circulation drilling is becoming increasingly popular around the globe. In fact, it`s the most widely sampling method. This is largely due to our innovative designs, and we`re continuing to develop the capabilities of this valuable sampling method. We also provide full range of technical support including product selection, technical advice and the on-site service.

Mining roatry tricone drill bit always used for the drilling of the production hole in open pit mining. According to different rock formation, there should be used corresponding type IADC Code products. Black Diamond with over 24 years experience in the manufacturing of rock tools, now self designed and produced the mining tricone bits that cover the most common used sizes.
