Master Proper Usage to Improve the Efficiency of Diamond Geological Drill Bits
In drilling operations, improper use of diamond geological drill bits can easily lead to problems such as bit burning, sticking, and matrix cracking. Using them correctly and scientifically not only helps prevent these failures, but also significantly improves operating efficiency and extends service life.
Proper Installation and Operating Guidelines for Diamond Geological Drill Bits
Pre-use preparation
After unpacking a new diamond drill bit, carefully inspect its overall condition, with special attention to possible thread deformation. Check each joint and outer tube in the drill string one by one to ensure all threaded connections are clean and free of debris, and confirm that the core barrel and casing show no severe wear or cracking. Once all parts are verified to be in good condition, apply lubricant to the threaded connection of the bit and tighten it smoothly in place.Operating practices during use
To keep the cutting edge sharp, select a diamond bit with matrix hardness matched to the formation characteristics. For detailed selection guidance, consult our company. During drilling, maintaining normal circulation of flushing fluid or drilling mud is essential to reducing wear on both the drilling tools and the bit. After normal penetration begins, do not apply excessive weight abruptly, as this can cause rigid damage to the bit. The rig supervisor should closely monitor drilling conditions throughout the process to prevent rock fragments or foreign matter from entering the hole and damaging the bit.Post-use maintenance
After drilling is completed, lift the drill string to the surface promptly to avoid sticking incidents. At the end of the job, remove the bit from the core barrel or casing and store it properly to prevent thread contamination by chips or debris, which may affect tightening during the next installation. If the bit will not be used for an extended period, clean it thoroughly, apply anti-rust oil, and then package it for storage.
Although diamond geological drill bits are now more affordable than before, proper use and standardized maintenance should still be treated as routine operating fundamentals. Only by following scientific operating methods can each bit deliver full performance, sustain high drilling efficiency, and achieve a longer service life.
