Power Torque: Our power torque feature allows you to quickly increase the torque on your rotation unit with just a few clicks. Press the designated button on the rotation joystick (for manually controlled rigs) or on the side of the radio control transmitter (for fully radio-controlled rigs) to activate the feature. You can also use the iQDrill screen to enable the function for a longer duration.

Turbo Feed: Our 6-meter drilling rigs are equipped with a convenient Turbo Feed feature that allows you to speed up the quick feed process for faster pipe changes. Press the designated push-button on the feed joystick (for manually controlled rigs) or on the side of the radio control transmitter (for fully radio-controlled rigs) to activate the feature temporarily, or use the iQDrill screen to enable the function for a longer duration. This feature is designed to streamline the drilling process and help you work more efficiently.
