Anti-Torque Swivel
The Anti-Torque Swivel by InFocus can be used in conjunction with drilling motors on service/workover rigs instead of power swivels. Common uses are drilling out cement, retainers, bridge plugs or stage collars.
Designated as a Combination Circulating Head and Screen Sub, the swivel works off of pump pressure. In pump-on mode, lockup occurs, taking up reactive torque of the motor.
Drill string will rotate freely in both directions until the mud pump is engaged. Lockup is in effect until the pump is disengaged, allowing free rotation for connections.
