TEI Rotary Shock Subs are designed to prevent metal-to-metal contact between the drill head and the drill string. The hardened rubber inside our rugged shock sub assists in reducing shock in the axial and the torsional plane.

This tough TEI drilling component increases the lifetime of all rotary heads by reducing the amount of shock produced by down-the-hole hammers, tricone bits and augers.
