About this product

The SRS is the auger boring market’s first steerable head designed to navigate not only solid rock but difficult fractured rock conditions as well. Engineered to operate in rock up to 25,000 psi, the SRS allows operators to keep bores on line and grade even in the toughest ground conditions for an on-grade bore.

Key Features


The full-rotational turntable eliminates the need for a single main bearing that can seize up and freeze the head. The SRS also incorporates an automatic grease system that constantly lubricates the turntable for maximum uptime and productivity.

Efficiency on the Job. Completes longer on-grade bores compared to other methods, at a reduced cost, while helping contractors complete more bores in a time-efficient manner.


A system of both disc cutters and rock picks work to navigate varying rock conditions. The disc cutters are designed to break up solid rock as they rotate. The rock picks are used to pull any remaining fractured rock the disc cutters could not disperse in order to produce a clear bore path.


Four steering flaps that are hydraulically actuated allow the head to stay on-grade

Monitor. Check and maintain the line throughout the bore with twin line projection halogen lights enclosed in the steering head
Self-Contained Control Station. Self- contained control station controls the movement of the steering head and all hydraulic, water and electrical lines.


A half-open faced design allows fractured rock to be pulled into the cutting head where it is either crushed or swallowed, creating a consistent boring path in the process. A system of both disc cutters and rock picks work to navigate varying rock conditions.
