Frequent rotation in the directional well forms a keyway, and the drill rod is stuck in the keyway. Preventive measures: Regularly perform short trips to repair the wellbore and control dogleg deviation..

Before drilling, inspect the condition and lubrication of all drill string components, including the hammer or drifter. Replace any worn out parts, following manufacturer’s recommended discard limits closely. Snake skin is a wear pattern of micro cracks that develop from drilling fatigue in non-abrasive rock..
This chapter contains some common types of failures occurring on DTH drilling tools For most failures we can identify it’s probable cause and typical supporting evidence.
Rod connection and removal are crucial aspects of down-the-hole drill operations, directly impacting overall work efficiency and the service life of rock drilling tools..
It was possible that the rig was drilling in severe drilling conditions, or that the driller was pushing too hard or had a poor drill string design. I asked some questions as to hole sizes, depths, etc.
[pdf] Fill the reservoir with air tool oil or 10W equivalent for 9 lb and 15 lb class. Use rock drill oil for the 38 lb and 60 lb class tools. Check all nuts and bolts to ensure they are tight on the tool. Make sure retainer locks into place. Replace retainer and springs if worn.
