PETOL™ Rig Wrench

The PETOL™ RIG WRENCH provides a faster and safer method of making up or breaking out drill pipe on water well and blast hole drilling rigs. The wrench is self-adjusting with non-jamming ratchet action. Specially designed hand grips enable the operator to apply and remove the wrench with ease. The added expense of hook jaw and insert breakage is greatly reduced through the PETOL Rig Wrench’s nonjamming feature and rugged design. Because PETOL Inserts are seated in dovetail slots, they will not shear from the wrench during use.
