    Kelly Saver Subs
    The Kelly Saver Sub is used to extend the life of the kelly by taking the connection wear each time it is made up to a drill stem component. The saver sub connection is sacrificed because it can be easily repaired or inexpensively replaced. The saver sub can be equipped with a rubber or brass protector to reduce BOP equipment and casing wear resulting from contact damage with the lower kelly connection. Kelly Saver Subs are manufactured from 4145M or 4140HT material grades.
