1 Junk Subs are designed to remove debris too heavy to be circulated out of the hole and are normally positioned in the drill string, just above the drill bit or mill. In operation, the debris is brought up from the bottom by this circulation and drops over the lip into the cup as the circulation slows, allowing the denser material to drop back. The Junk Sub is fabricated from high quality steel, incorporating Rib Guides to prevent the cup being crushed. Junks Subs are available in three different cup lengths, the selection depending on the capacity required. If increased capacity is required several Junk Subs can be made up above the drill bit or mill. Junk Subs are avaible with right and left thread and can be custommade to Customer specifications. 1 Junk Subs www.dmz-eng.com 1 «DMZ Engineering», 8-A, Lodzinskaya str.
