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. 

Exchangeable motors offer various torque / rpm combinations 

Hardened internal components last longer in production drilling applications 

  • Single drive shaft reduces wear and maintenance requirements.
  • Engineered simplicity increased power without increasing size.
  • Extended durability reduces the need for up to three competitor drill heads, reducing carbon emissions.
