The Rock Drill R407 Drilling Rig is a powerful limited access drilling rig with low maintenance requirements. Built to handle high torque, restricted access drilling projects the Rock Drill R407 is a versatile drilling unit.

With modular drill head and clamp system options the Rock Drill R412 can be optimized to increase penetration rates even in the worlds toughest drilling conditions.


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.
