Temporary steel casing is push down first and then start drilling...or it both go down together? If it is together, how the casing being tied to the odex system?
The drill bit would go down together with the temporary casing. It is quite hard to explain here, how the odex system works. Probably we save it for another vlog. Thnx
Good and clear explanation, Brovo
