Dynomax Shock Subs

During drilling operations, the drill bit imparts various dynamic impact loads to the drill string. These loads
are cyclical in nature and can lead to premature failure of the drill string & rig equipment, and lead to low ROP & hole problems. These translate into higher drilling costs.

Dynomax Shock Subs are designed for a wide range of drilling environments and extreme conditions. Shock Subs improve the life and durability of the drill string assembly, improving online efficiency and operating costs.

The Shock Subs are available in sizes:

4 3/4″ (121 мм)
6 3/4″ (171 мм)
8″ (203 мм)
9″ (241 мм)
