This is an invention of mine to which I have a copy write with patent pending. Its title is self explanatory, the required presure for drilling the necessary holes for Closer Arm brackets, Overhead Stops & Coordinators in commercial hollow metal door frames can be back braking and needless to say when under a drill without the help of the DRILL PRESS (Direct Reverse Inverted “L” Lever commercial door drill Press the white hot metal shavings burn and are a safety hazard. With the help of the DRILL PRESS (Direct Reverse Inverted “L” Lever commercial door drill Press)you save energy, pain and the chance of injury. Horizonal Commercial Door Drill Press coming soon.
