The core function of a reverse impact hammer is to resolve drill string jamming issues during drilling operations and assist in clearing obstacles inside the borehole, ensuring the drilling process remains uninterrupted.

Its main roles can be broken down into the following 3 points:

Addressing drill jamming faults: When the drill string (such as drill pipes or drill bits) gets stuck in the borehole by sand, cuttings, falling rocks, etc., and cannot be lifted, lowered, or rotated normally, the reverse impact hammer can use downward impact force to loosen the stuck part and restore the drill string's mobility.

Clearing downhole obstacles: If there are large rock fragments, collapsed soil layers, or other foreign objects in the borehole, the reverse impact hammer can repeatedly impact to crush, compact, or push the obstacles out of the borehole, opening up the drilling channel.

Assisting in breaking hard formations: When encountering locally hard rock formations that reduce drilling efficiency, the impact force of the reverse impact hammer can work with the drilling force of the rig itself to assist in breaking the hard formations, reducing drilling resistance and improving operational efficiency.

Would you like me to compile a comparison table of usage methods for reverse impact hammers in different scenarios, such as specific operating steps for drill jamming, obstacle clearing, and hard formation breaking
