The "MagicDrill" makes it possible for you to let the head of the screw disappear in the surface of the sign. The system is adjustable to any deepness you want to screw the screws into.
The ball bearing mounted plate doesn't rotate  and so a damaging of the surface will be prevented.
Within the scope of supply you get a "MagicDrill", 2 Allen keys for aligning, 8 "SignScrews" - 76,4mm (3 inches) and a couple of our "SuperSignCaps".
