摘要

A drill system for use with a drill rod includes a support member, and a drill assembly movably associated with the support member and configured to be connected to the drill rod. The system further includes a centralizing device movably associated with the support member and configured to receive the drill rod. The centralizing device includes a movable jaw and a latch arm connected to the jaw and configured to move the jaw between an open position and a closed position for retaining the drill rod. Furthermore, the latch arm has a locking feature configured to hold the latch arm in a locked position to thereby hold the jaw in the closed position.
