Rotary drilling rig core bit is suitable for extremely hard formations with good integrity, and has the advantages of smooth drilling and less damage to the rig.

Rotary drill coring bit

Precautions for use of rotary drilling rig core bits:

1) Confirm whether the barrel drill is firmly connected to the drill pipe and whether the teeth are intact, because the rock drilling has a large vibration and destructive force on the rotary drilling rig, and a double pin connection is required.

2) Determine the footage according to the formation and torque resistance. If the drilling resistance is suddenly reduced during drilling (generally, the core is broken), you can continue to drill 30-40cm, and then reverse a few turns to increase the core Success rate.

3) In the course of drilling, if the drill bit is found to be severely worn or damaged, it must be replaced in time, and the same tooth profile must be replaced.

4) Try to avoid using barrel drills as a fishing tool.
