drill rod and tool steel

Drilling equipment is essential in various sectors, including oil and gas, mining, construction, and environmental research. Each sector requires specialized machinery capable of performing specific tasks effectively. For instance, in the oil and gas industry, rotary drill rigs and downhole drilling tools are critical for accessing subterranean resources. In contrast, the mining sector demands heavy-duty equipment designed to penetrate solid rock and extract valuable minerals.

  • 1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.
