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.
“While drilling 360m deep RC precollars we experienced problems with deviation of more than 5 degrees at the end of hole. The Harlsan Spiral Sub dramatically improved accuracy, enabling us to keep the holes within 1-2 degrees.”
John Bartle, Operations Manager – Kennedy Drilling
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 Harlsan today to find out more about the Spiral Sub and our full range of Dig Out Subs.
