You’re a DIY kind of guy, doing stuff around the house with the power tools you had so much fun buying in Home Depot, right? Well, chances are you know just how hard it is to drill a hole that’s perfectly perpendicular to your surface. With the BullseyeBore drill attachment though, your problems might be solved. It uses a laser to project three circles onto your surface. As long as the three circles are perfectly equidistant, you’re drilling straight; deviate from that and you’ll immediately notice.
There are three patterns generated by BullseyeBore: a single dynamic position pattern, and two fixed circular measurement patterns. This is demonstrated in the video (left) and images (below) with the single dynamic position pattern as the outermost pattern, and the fixed circular measurement patterns on the inside.
The single dynamic position pattern changes shape dramatically when the drill is misaligned with the work surface, while the two fixed measurement patterns maintain consistent and evenly spaced concentric circles regardless of alignment.
A drill is properly aligned with the work surface when the single position pattern becomes circular and is concentric with the two fixed measurement patterns.
The BullseyeBore attachment also helps you know exactly how deep you’ve drilled, since the circles will change size as you go deeper, letting you keep track of your progress.
It’s not available for purchase yet, but there are two versions planned: one that attaches to the chuck of any drill and accepts bits on the other end, and one that’s actually integrated into a chuck directly. The company is looking for partners to bring it to market.
