TCI Tapered Tool Hole Opener Trenchless Well Rock Drill Reamer Hdd Hole Opener
1. Straighter hole - Drill a smaller hole by using a "pilot" bit and then attach that bit to the bottom of the hole opener. The hole opener will follow the path of the hole by a smaller bit.
2. Larger holes and Smaller RIGS - By drilling in stages, larger holes can be drilled using a smaller rig. Smaller holes require less power.
3. Tool replacement and cutting cost - In most hole opener designs, the tool can be easily replaced. The cost of tool replacement is a fraction of the cost of replacement for a large horn bit.
4. Cost of Large cuttings bits - Larger diameter cuttings bits are not only expensive, but can also be difficult to find. A more economical solution is to use a triangle bit segment using a smaller opener..
5. Flexibility -- Openers can be manufactured to almost any size and can be configured to drill through any formation.

1. The opening device has the advantages of good tooth position distribution, good wear resistance, large cutting area and high efficiency.
2. The hole opener adopts internal and external anti-drip device to reduce the occurrence of tool falling accidents in harsh drilling environment.
3. Roller bearings and larger cross section are used for cutting tools and rubber seals to improve the service life of the hole opener.
4. The directional sheet guides and supports the body, and the surface adopts wear-resistant alloy to improve the wear resistance and impact resistance.
