Matrix Toubleshooting: Outside Diameter Wear

Posted by Rod McCoremick on Jul 3, 2017 2:00:00 PM

Over this year we have done a few blogs on matrix troubleshooting where we have examined the different wear patterns on a bit crown. The wear profile provides clues as to why your core bit may be underperforming. By changing drilling parameters or making other simple changes, you may be able to improve drilling performance. Not long ago, one of our blog subscribers mentioned having problems with gauge loss on the outer diameter. Let’s look at some of the causes and some of the solutions.
