This feature will detect the rock when the bit touches the ground and start your air, dust suppression, rotation and feed to collar the hole. After the collared distance has been met, this control will adjust air, dust suppression, rotation and feed to a drilling setting. AutoDrill 2 will apply optimal pulldown and rotation to drill as fast as possible without stalling the rotation or get stuck. Once the target depth has been reached, AutoDrill 2 will clean or flush the hole, shut off the air and dust suppression, and the return the bit to a tramming position. AutoDrill 2 provides the consistency of drilling to the corect hole depth, including water flow to maintain the hole so it does not collapse.
