Horizontal Directional Drilling Done Right.


StraightLine specializes in the design, development and manufacture of equipment for the Horizontal Directional Drilling Industry. Regardless of the brand of drill, size of drill or the ground conditions, we are committed to make your HDD operation the very best it can be.

This commitment starts with experience, 30-years to be exact. StraightLine produced its first directional drill in 1989. Since that time, StraightLine has manufactured nearly one thousand drills and accumulated many thousands of hours of hands on drilling experience. Our product specialists have drilled in every ground condition that creation could throw at us in locations all across North America, Australia, Europe and Asia.

As the HDD industry has continued to grow and mature, so has the StraightLine brand. We now manufacture the industry's most extensive range of HDD products. These products include a wide range of "in stock" items as well as an unlimited combination of custom built products.

Our stock inventory items primarily target American Augers®, Astec®, Case®, Ditch Witch®, Robbins®, StraightLine® and Vermeer® brand equipment. We have the capability to cut 78+ thread types common to the HDD industry, from Ditch Witch® JT520 to 6 5/8" FH, with new connections being added as the industry expands.
