DRILL STRAIGHT
BullseyeBore Core solves the problem that every drill user has: how to drill straight (perpendicular to the worksurface). It projects a series of circular patterns on the worksurface that indicate alignment or misalignment of the drill bit with regards to the worksurface. When the patterns are concentric, the drill is straight with (and perpendicular to) the worksurface. Conversely, when the patterns are non-concentric, the drill is misaligned with the worksurface. These patterns make it easy for DIYs and Pros alike to always drill straight.
ANY ORIENTATION
BullseyeBore Core works in any orientation, so it can easily be used on walls, floors, ceilings, or boards at any angle. The Core’s unique shape also allows it to be virtually invisible during drill rotation, so the drill bit, worksurface, and the Core’s projected worksurface patterns are clear and easy to see.
Safe to Use
If a foreign object mistakenly comes into contact with BullseyeBore Core during rotation, the connection between BullseyeBore Core and the drill chuck is immediately broken, and the Core’s rotation ceases (even if the drill bit is still spinning). Please read and follow the BullseyeBore Core Safety Guidelines before attempting to use BullseyeBore Core.
Works With Your Drill
Bullseyebore Core was designed to work with thousands of common standard electric drills and drill chucks. For information regarding use with your specific drill, see the BullseyeBore Core Product and Accessory Compatibility Guide for more information.
Non Contact
Unlike traditional drill guides, drill cups, or drill blocks, Bullseyebore Core does not need to contact the worksurface you drill into, and thus will not scratch or mar it during normal operation. Further, unlike traditional drill guides, drill cups, or drill blocks, BullseyeBore Core does not block or obstruct your view of the drill bit or worksurface during a drilling operation.
