Tricone Bits Shelf Life.
31 January 2019 Due to the war in Yemen, the Drilling Operation was suspended in April 2015; as result of that, we have a good amount of 17.1/2", 12.1/4", 8.1/2" and 6" tricone bits (major brands) in the warehouse, most of them were purchased between 2010 and 2015. I am looking for comments and recommendations regarding the use of these bits exceeding the published manufacture's shelf life. I am aware of the potential risks published by manufactures, however, I would like to have experience based comments and recommendations from the community.Most of these bits were the latest generation at the time with features to drill tough and abrasive formations
