TEI Rotary Shock Subs are designed to prevent metal-tometal 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 absorbed by the rotary head.
