The JT200 Series Rotation Heads have 2 set speeds with variable speed control in between. The high torque/low speed and low torque/high speed settings allow the operator to alternate the drill head’s power and speed for different applications and drill methods. A 2-3/8″ center bore allows for mud or air flushing with the optional 2,500 PSI 90 degree swivel.
The JT200-M Series Drill Heads are built to last with hardened internal components that are designed to stand up to the worlds toughest drilling conditions.
With minimal maintenance requirements and exchangeable top motors, the JT200-M Series offers torque and RPM combinations for multiple applications to optimize your penetration rates.
The JT200 Series Drill Head was first engineered and built in 1992 for high torque drilling applications. To reduce wear and breakdowns the JT200 drill head was built with a solid main shaft. This increased it’s durability and it has since stood up to some of the toughest drilling conditions in the world.
