DRILL STRAIGHT -- Projects a series of circular patterns on the work surface to indicate alignment or misalignment of the drill bit. When the patterns are concentric, the drill is straight and perpendicular to the work surface. ANY ORIENTATION -- Functions in any orientation, suitable for use on walls, floors, ceilings, or angled surfaces. The unit's unique design minimizes visual obstruction during drill rotation, allowing clear visibility of the drill bit, work surface, and projected patterns. SAFE TO USE -- Automatically disengages if an obstacle is encountered during drilling. COMPATIBLE WITH MOST DRILLS -- Designed to work with a wide range of standard electric drills and drill chucks. NON-CONTACT DESIGN -- Unlike traditional drill guides, cups, or blocks, it does not contact the work surface, helping prevent scratches or damage. Additionally, it does not block or obstruct the view of the drill bit or work surface during operation.
