DRILL STRAIGHT -- It projects a series of circular patterns onto the work surface that indicate the alignment or misalignment of the drill bit relative to the work surface. When the patterns are concentric, the drill is straight with (and perpendicular to) the work surface.

ANY ORIENTATION -- It works in any orientation, so it can be easily used on walls, floors, ceilings, or boards at any angle. Core's unique shape also means it is virtually invisible during drill rotation, so the drill bit, work surface, and Core's projected work surface pattern are clear and easy to see.

SAFE TO USE -- It safely disconnects if an obstruction is encountered during drilling.

WORKS WITH YOUR DRILL -- It is designed to work with thousands of common standard drills and drill chucks.

CONTACTLESS -- Unlike traditional drill guides, drill sleeves, or drill blocks, it does not need to make contact with the work surface you are drilling into and therefore will not scratch or damage it during normal operation. Additionally, unlike traditional drill guides, drill sleeves, or drill blocks, it does not block or obstruct your view of the drill bit or work surface during a drill.
