When activated, this function 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. This feature will apply optimal pulldown and rotation to drill as fast as possible without stalling the rotation or getting stuck. Once the target depth has been reached, the Auto-drill will clean or flush the hole, shut off the air and dust suppression, and then return the bit to a tramming safe position. This feature provides the consistency of drilling to the correct hole depth, including water flow to maintain the hole so it does not collapse. Currently this is available for single-pass drilling and multi-pass drilling, although a manual rod change must be made at this time.
