2.Larger Holes with Smaller Rigs - By drilling a hole in stages, larger holes can be drilled with smaller rigs. A smaller hole requires less power.
3.Replacing Cutters and Cutting Cost - On most Hole Opener designs, the cutters can be easily replaced. The cost to replace a cutter is a fraction of the cost to replace a large tricone rock bit.
4.Cost of Large Rock Bits - Larger diameter rock bits not only cost a lot, they can be difficult to find. A more economic solution is to use a hole opener that uses smaller tricone rock bit segments.
5.Flexability - Hole Openers can be fabricated in just about any size, and can be configured to drill through any formation.
