API Standard Hole opener for rock gas oil well drilling
Hole opener drill bit
Hole openers are designed for the enlargement of pilot holes and large hole applications. They are also used for road and river crossing application. The hole openers are manufactured from AISI 4145H fully heat-treated alloy steel. All are available with carbide-milled teeth and insert cutters. Arms and cutters are hardfaced for protection in three different designs for varying conditions and rock formations. The design of the hole opener allows for field-changing the cutters.
The Hole Opener Advantage
1.Straighter Holes - By drilling a smaller hole with a "pilot" bit, then attaching that said bit onto the bottom of the 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 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
