Proper drill bit selection and operation are crucial for optimal performance and safety. Key considerations include:

• After completing the drilling structure, promptly replace the central drilling tool. First clean the hole bottom and remove residue before slowly lifting the drilling tool when the lifting force is just sufficient.
• Continuously monitor and summarize drilling progress. Observe casing follow-up and hole conditions, maintaining cleanliness as needed. Never force the drill bit during operation.
• When rock slag accumulates at the hole bottom and affects eccentric bit retraction, apply air pressure to clean the hole, briefly operate the DTH hammer, then lift the central drilling tool again.
