A Guide to Help You Extend the Life of Your Core Bit

posted by the Epiroc Exploration & OreBody Solutions team

April 9, 2020

There is a lot of negative news circulating, so we thought it would be a good time to launch a new, free guide available now for download. Our newest publication is the Diamond Drillers’ Guide to Extending Core Bit Life. It provides a lot of information and advice on how to get the most life out of your core bit. We touched upon this topic a while ago in a blog, but this guide has a lot more information that has been requested often since we wrote the blog.


Getting the longest life possible for your core bit is key if you want to run a productive and profitable drilling operation. Changing a drill bit takes time especially the farther down the hole it is, and the time spent replacing a bit is not useful. This new guide discusses the importance of choosing the right matrix and configuration, how to handle and take care of your bits including some common mistakes and the role of drilling parameters. The guide also explains how to sharpen core bits and how to troubleshoot matrix wear patterns. Finally, the importance of using drilling additives is also discussed.


Our guides offer a great opportunity to learn how to deal with common drilling issues and this is our 15th guide. I encourage you to check them all out here where they are free and available for download. Some guides are available in other languages and we have a selection of case studies and videos as well.


Epiroc is continuing operations during these changing times and we are ready to help you while keeping a safe distance. If you are facing drilling challenges, our technical support team will do its best to help you with advice and guidance. Feel free to reach out to them. Our goal is and remains to help improve drilling performance and accelerate the transformation of our industry.
