Operational Guidelines
- Replace central drilling tools promptly after completing drilling structures
- Thoroughly clean hole bottoms and remove residue before tool changes
- Monitor casing follow-up and maintain hole cleanliness during operation
- Avoid forceful extraction of drill bits during operation
- Address rock slag accumulation promptly with proper cleaning procedures
For optimal performance in water well drilling applications, proper drill bit selection and operation are crucial.
