Tricone Hole Opener with large range size
Tricone hole openers can prove to be a great cost effective solution due to the cost and limited availability of large diameter bits. They also enable larger holes to be drilled with smaller rigs by drilling in stages.
Hole Opener diameters range for 8″ to 48″ with different pilot hole diameters and custom builds to suit your ground conditions.
