The patented drill accessory, BullseyeBore Core, allows for always drilling straight. It can be magnetically attached to the flat front of the drill chuck and rotates with the drill. In doing so, it projects circular patterns onto the work surface, indicating a correct or incorrect alignment of the drill. BullseyeBore Core can be used in any orientation, on walls, floors, ceilings, or angled boards. Upon contact with a foreign object, the magnetic connection safely disconnects, and the rotation stops.
