StraightLine HDD recently expanded its hole opener offering with the introduction of the XL-I Series. Designed from the ground up for horizontal directional drilling, the XL-I Series is positioned as a cost-effective alternative to "split-bit" hole openers.
At the core of the design are proprietary cones—available in six sizes, in either Tungsten Carbide or Mill Tooth configurations. Mounted to a purpose-built platform, the design facilitates load transfer to the shaft and bearing, with minimal radial load. The result is a dramatic improvement in production, service life and consistency, bore after bore.
Next, designers set out to address wear and performance characteristics by re-examining the interplay between cone diameter, height and carbide placement. Cones are sized and attached to the baseplate at an angle that protects vulnerable surfaces. Shortened cone height further improves wear resistance. Carbides placed to cut independent paths yield higher efficiency and longer service life.
Internally, the cone's proprietary sealing and bearing system mitigates fluid intrusion, yielding a myriad of user benefits, from reduced torque and fuel consumption to extended tool life.
As a platform, the XL-I Series incorporates design characteristics that ensure the tool's original geometry is maintained—even after rebuild. This approach yields consistent and repeatable performance.
The XL-I Series includes six sizes, from 12.75- to 24-inches with IF Box x Box shafts.
