Work surface alignment — in other words, drilling straight — is tricky for the DIY-inclined layman. BullseyeBore makes this task more intuitive thanks to a drill-mountable transparent disk that projects a series of three concentric circles onto the drilling surface using lasers. If your drill is misaligned, the outermost circle skews towards one side and changes shape dramatically to let you know. Visual cues as to the depth of the drill bit are also provided, since the outermost circle also shrinks as the bit goes deeper, with the two innermost circles staying constant and acting as a reference.
