Bullseyebore | Cool Tool

  • by

Here is an interesting new tool. It’s called the bullseyebore and is a laser guide for your cordless drill.

There are three patterns generated by BullseyeBore: a single dynamic position pattern, and two fixed circular measurement patterns. 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.

You can also use the bulls eye drill to determine the drilling depth. After a drill is aligned and pressed into the work surface, the circle produced by the single dynamic position pattern becomes smaller.  For example, if the diameter of the circular position pattern is 4.0 inches at the start of a drilling operation, and the ending diameter is 3.5 inches, then the drill bit has penetrated 0.5 inches into the work surface.

Another way to use a cordless drill as a drill press was covered in a previous post. You will need to setup and build this one but the results for drilling straight down might be more consistent. Jimmy DiResta – Cordless Drill Ideas
