BullseyeBore Core CR1-101 Drill Guide for Straight Holes - Magnetic Drill Attachment with Efficient Red Laser for Visual Worksurface Alignment - Compatible with Common & Specialty Bits from 2" to 8"

DRILL STRAIGHT EVERY TIME: BullseyeBore Core projects laser circles onto your work surface as you drill. Concentric circles = you’re aligned. Non-concentric = adjust. No guesswork, no crooked holes - just real-time visual feedback that works on walls, floors, ceilings, and any angle. Unlike bubble levels, it doesn’t depend on gravity. The Core must be rotating on the drill to project laser patterns - it is not active when stationary. INDOOR & WORKSHOP USE ONLY - IMPORTANT BEFORE YOU BUY: Not visible in sunlight or outdoors. It is designed for indoor, garage, and workshop conditions and delivers up to 9 hours of battery life per session. If you need visibility in bright workspaces or on dark work surfaces, see the BullseyeBore Core Green (CG1 series). EXTENDED MODEL - BITS FROM 2" TO 8" INCLUDING SPECIALTY BITS: The CR1-101 supports standard bits plus spade, auger, step, and aircraft extension bits from 2" to 8“. For bits over 4”, the extended model is required. Uses LR44 coin cell batteries (included). WORKS WITH THE DRILL ALREADY IN YOUR TOOLBOX: Magnetically attaches to thousands of common commercial electric drills in seconds - no tools, no modifications. Important: not compatible with rotary hammer drills, SDS drills, non-metallic chucks, or hole saws. Hex shank and impact drills require the Chuck Alignment Guide (sold separately). WORKS IN ANY ORIENTATION - WALLS, FLOORS, CEILINGS, ANY ANGLE: Unlike gravity-dependent bubble levels, BullseyeBore Core drills straight into any surface at any orientation. Overhead, vertical, angled - position doesn’t matter. Snap on and drill straight. SAFE BY DESIGN - STOPS SPINNING BEFORE IT STOPS YOUR WORK: BullseyeBore Core attaches magnetically to your drill chuck. If anything contacts it while spinning, the magnetic connection releases instantly - the Core stops, your drill and bit keep going. Unlike a physical drill guide, it does not reside on your work surface. No scratches, no marks, no damage to finished surfaces.
