This means that the connection between the top end of the Saver sub and Kelly is seldom used, and suffers minimal wear and tear, whereas the lower connection is used in almost all cases displacing the most wear and tear from the rotary head connection to the much cheaper Saver Sub which is expendable and reduce cost.Straight OD SubStraight OD Sub is used to connect drill stem members that have a similar outside diameter. The drill bit, downhole tools, heavy weight drill pipe and drill pipe can be crossed over using a straight OD sub.Reduced Section SubReduced Section Sub is used to connect drill stem parts that have different diameters. This sub can be used to crossover large ODdrilling tools or a tapered drill collar string.
