A 20mm drill rod typically refers to a cylindrical tool made of high-strength steel, designed for use in drilling operations. Its 20mm diameter strikes a balance between robustness and manageability, allowing it to penetrate materials while maintaining sufficient structural integrity. The rod can be produced in various lengths, which can be tailored to the specific requirements of a drilling project. Additionally, many manufacturers offer drill rods with various coatings or treatments to enhance wear resistance and durability, making them suitable for use in harsh environments.

At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

First, the classification of drilling RIGS:
1, according to the use of the address is not the same, the drill can be divided into underground and open air two categories. According to the presence or absence of traveling structure, the drilling rig can be divided into self-propelled type and non-self-propelled type. There are many open-pit drilling RIGS in China, most of which are self-propelled.
2, according to the aperture is not the same, the drill can be divided into light drilling rig, medium drilling rig, heavy drilling rig.
