Key Points for Choosing High-quality Drill Bits

In the operation of rotary drilling RIGS, the drill bit is the "vanguard force". Selecting the right high-quality drill bit can significantly enhance construction efficiency and reduce costs. The following six key points for selection will help you precisely pick a good drill bit that suits you.

1. Identify the geological conditions: Different strata correspond to different drill bits. For soil layers, rotary buckets are used; for pebble layers, short spiral drill bits are selected; and for rock layers, truncated drill bits are relied upon. Only by choosing as needed can efficient rock breaking and soil extraction be achieved.

2. Pay attention to the diameter of the drill bit: Select the drill bit based on the diameter of the pile. A diameter slightly smaller than that of the pile is sufficient. If it is too large, it will increase resistance and wear out the drill bit; if it is too small, it will be difficult to meet the design hole diameter standard.

3. Check the material and process: High-quality drill bits are made of high-strength alloy steel, with the tooth seats welded firmly and a thick wear-resistant layer. Observe whether the weld seams are uniform and full, and whether there are cracks or sand holes in the material.

4. Consider the structure of the drill bit: A reasonable design of the slag discharge channel is crucial, as it can accelerate the discharge of construction waste. The structures such as double-bottom sand hopper and open-door drill bit can optimize the drilling efficiency according to the working conditions.

5. Compatibility with drilling rig models: Rotary drilling RIGS of different power levels have different torques. It is necessary to ensure that the drill bit is compatible with the power of the drilling rig. Excessive weight of the drill bit or excessive torque demand will affect the stability and service life of the drilling rig.

6. Refer to brand reputation: Choose a brand with industry experience and perfect after-sales service. Reliable brand drill bits have quality guaranteed, and in case of problems, technical support and spare parts supply can be obtained in a timely manner.

In conclusion, choosing the right high-quality drill bit requires a comprehensive consideration of geological conditions, specifications, quality, structure, equipment matching and brand. Only when all aspects meet the construction requirements can the rotary drilling rig exert its maximum efficiency and ensure the smooth progress of the project.
