BullseyeBore Core CR1-101 Magnetic Red Laser Drill Guide, Drill Straight

Product Information

About this item

• DRILL STRAIGHT, PERPENDICULAR HOLES WITHOUT A DRILL PRESS: BullseyeBore Core projects laser circles onto your work surface, keeping your drill square even on angled and sloped surfaces a bubble level can’t read. Concentric circles mean aligned; non-concentric means adjust. It works only while spinning: run your drill at moderate-to-high speed and the full circles appear on the work surface.
• INDOOR & WORKSHOP USE ONLY, IMPORTANT BEFORE YOU BUY: Not visible in sunlight or outdoors. Built for indoor, garage, and workshop work: interior cabinets, trim, finished and overhead surfaces, with up to 9 hours of battery life. Need bright-workspace visibility? See the BullseyeBore Core Green (CG1 series).
• EXTENDED MODEL, MAX BIT 8" LONG, 1/2" DIAMETER: Supports standard bits plus some spade and auger bits. For bits over 4", the extended model is required. Uses LR44 disposable coin cell batteries (included).
• WORKS WITH THE DRILL YOU ALREADY OWN: Magnetically attaches to thousands of common electric drills in seconds, no tools, no mods. Fits standard cordless drills and hammer drill drivers. Not compatible with rotary hammer (SDS / SDS-Plus) drills or hole saws. Impact or hex-shank driver? The Chuck Alignment Guide (sold separately) makes it fit.
• WORKS WHERE A BUBBLE LEVEL CAN’T, ONE-HANDED: A bubble level only knows gravity, so it fails on vertical, angled and sloped surfaces. BullseyeBore reads the surface itself and keeps your drill square at any angle. One hand, no separate guide to hold and no bulky jig to clamp, so it’s easy to control even overhead.
• SAFE BY DESIGN, DISCONNECTS THE INSTANT ANYTHING BLOCKS IT: BullseyeBore mounts magnetically to your drill chuck, so any obstruction encountered while spinning releases it instantly and your drill keeps going. It never needs to touch your workpiece, so no scratches or marks on finished surfaces.
• THE GIFT FOR THE PERSON WHO’S ALWAYS GOT A PROJECT GOING: Works with the drill they already own, arrives ready to use, and solves a problem they’ve had for years. Ideal for birthdays, Father’s Day, holidays, or any occasion where you want to give something genuinely useful.
• RED DOT DESIGN AWARD WINNER, 17,000+ UNITS SOLD: Backed by 4,300+ Kickstarter supporters before launch. Customers call it ‘the missing tool in the tool chest.’ 1-year manufacturer warranty, US-based support.
