The HOLE Depth readout displays the exact depth of the hole to the nearest tenth of an inch. Know exactly how deep your hole is, NO more over or under drilling holes. Bit Depth readout lets you know exactly where your bit is in reference to the bottom of the hole. Also know exactly where a seam is to aid in loading holes.
