36" hard rock hole opener/oil well reamer bit with tricone plam bit for hole enlarging
Our hole opener bit advantage
1.Straighter Holes: By drilling a smaller hole with a"pilot"bit, then attaching that said bit onto the buttom of the hole opener. The hole opener will follow the path of the hole drilled by the smaller bit.
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 bit: 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.HDD hole opener drill bit for water well drilling.
Recommended Drilling Parameter
Soft formations with low compressive strength and high drillability, such as mudstone, gypsum, salt, soft limestone, etc.
Medium hard formation with high compress strength, such as hard shale, limestone, sandstone, dolomite. etc
Hard formations with high compressive strength, such as sandstone, limestone, dolomite ,hard gypsum, marble, etc.
Soft to medium formations with low compressive strength , such as medium soft shale, hard gypsum, medium soft limestone, medium soft sandstone, soft formation with harder interbed, etc.
Note: The upper limits of WOB and RPM in above table should not be used simultaneously.
