For those of us who work with rotary drilling rigs, mastering the installation of drilling tools is essential, and we must also know how to use appropriate drilling tools for different geological conditions during drilling and piling. Many people experience slow hole-forming speeds or even wear and tear on the drill bit and rotary drilling rig because they haven't chosen the right drill bit. Therefore, properly selecting the drilling tools for a rotary drilling rig is crucial for successful hole formation.#drilling rig spare parts#
The drilling tools installed on small rotary drilling rigs must have a certain degree of rigidity to minimize movement and shaking during drilling and other operations. The installation of the drilling tools must conform to the rotary drilling rig manufacturer's standards. Various specifications and sizes of drill bits, such as short auger bits, rotary buckets, core drill bits, and core rotary drill bits, can be used during construction. Different rotary drilling rig drill bits should be selected according to different soil and geological conditions as follows: Short auger bits are suitable for cohesive soil, silt, sand, fill, and medium-density or higher sandy soil and weathered rock layers above the groundwater level. Core auger bits are suitable for gravelly soil, medium-hardness cores, and weathered rock layers. Core drill bits are suitable for weathered rock layers and cracked rocks. Rotary auger heads use mud slurry for wall protection and are suitable for cohesive soil, silt, sand, fill, gravelly soil, and weathered rock layers above the groundwater level.
I won't go into detail about selecting drill bit specifications for rotary drilling rigs; the specifications should be chosen based on the diameter of the hole to be drilled and the customer's requirements. Rotary drilling rigs offer flexible construction options, and drill bits can be changed at any time, making them very convenient.#drilling rig spare parts#
