Assembly Process – Self-drilling System
1° Insert the pilot drill bit, attached through stems to the perforator machine, into the first coating tube which contains the drilling crown.
2° Turn the pilot drill bit counterclockwise so that it clamps in the drilling crown. At this moment, the Inco Rock Casing system is ready for the drilling.
3° As drilling advances, join the coating tubes through male and female threaded connections until reaching the drilling length specified in project.
4° Upon finishing drilling, slightly turn it in the clamp opposite direction and remove the pilot drill bit.
5° Start a new drilling using a new coating tube with crown and the same pilot drill bit.
