Drilling Tools: Hole-openers

Hole-openers:

Rock bit hole-openers up to 920 mm (36 1/4 inch) in diameter are used for hole opening while drilling oil and gas wells, building oil & gas pipelines, as well as at any sites when technologically required. Hole-openers can be designed for soft, medium and hard applications; borehole is washed with water or drilling mud. A hole-opener combined with a pilot bit can replace a large diameter bit.

Several patented essential technical solutions have been used in hole-openers’ design. Hole-openers easy for use, reliable and cost-effective by reducing drilling time and cost.
