Horizontal Directional Drilling HDD Hole Openers Used to Enlarge Diameter Pr Drilled Hole



Hole Openers

Hole Openers are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes. A Hole Opener is sometimes referred to as a Reamer.

We are proud of the quality and workmanship of our custom built Hole Openers. All Hole Openers can be quoted with new/unused surplus or used Steel Tooth or TCI Cutters, as well as Hammer Bit Hole Openers.


DRILLING TYPE UNDERREAMER (DTU)

The Roschen DTU Underreamer has gone through several changes and modifications to adapt to the ever changing drilling applications and environments.

Features and Benefits:

1. Long proven history with over 2.5 million feet underreamed worldwide.
2. Expansion ratios 70% and larger than the OD of the body.
3. Hydraulically expandable with pump pressure.
4. Cutter arms move upward and out simultaneously in the body.
5. Reverse actuating mechanism maintains that tool is open while drill string weight prohibits tool closure.
6. Roller cone cutters are specifically designed for the ROSCHEN DTU underreamers and are consistent with down hole diameters.
7. Proprietary internal "cage" inside of roller cone cutters reduces wear and increases the life of the cutter.
8. Body machined from heat-treated steel bar, giving it exceptional strength.
9. Jet nozzles near the cutters allow for cutter washing and cooling.

10. Cutting Structures available include:

A. Sealed Bearing Mill Tooth
B. Sealed Bearing TCI
C. PDC
4. ROSCHEN's ADD Cutter
