What Does Drill Head Mean?

A drill head is defined as the cutting tool at the end of a drill string used to remove material and create pilot boreholes. Most drill heads are equipped with a nozzle capable of jetting high-pressure water to facilitate the drilling process.

The drill head can be manipulated via a steering tool on the drill string to adjust the direction of the drill path.


Trenchlesspedia Explains Drill Head

Various drill head types are available in the pilot-hole drilling process. The selection of the appropriate drill head is dependent on the ground surface geology and soil properties. Drill heads, such as a talon bit, contain multiple ports that jet water while drilling to assist in the removal of material.

After the drill head creates the pilot hole, back reaming can be performed to enlarge the hole to the appropriate diameter. Guidance and positioning of the drill head are critical as uncontrolled drilling can lead to unwanted damage and substantial rework.
