Product Description

Spiral Stabilizer Subs and Dig Out Subs for Reverse Circulation Drill Rods 
 

For dramatically improved accuracy, stability and on-target drilling, choose Roschen spiral stabilizer subs.



Introduction 
 

In developing the Spiral Stabilizer Sub Harlsan utilized cutting edge manufacturing technology to perfectly combine the role of Dig-out and Stabilizer Subs. The spiraling hard faced wear pads track an exact curve around the body of the sub. Results from extensive operational testing show the preciseness of this spiral enables stability and accuracy during drilling operations that isn’t obtainable with other subs.
 

As well as keeping deep Reverse Circulation holes on target the Harlsan Spiral Sub also significantly reduces drill string chatter.
 

Testimonial
 

While drilling 360m deep RC precollars we experienced problems with deviation of more than 5 degrees at the end of hole. The Roschen Spiral Sub dramatically improved accuracy, enabling us to keep the holes within 1-2 degrees.


This unique precision sub has enabled many of our customers to achieve drilling results that were otherwise unobtainable using conventional RC Dig-out or Stabilizer Subs. Contact Roschen today to find out more about the Spiral Sub and our full range of Dig Out Subs.
