- DRILL STRAIGHT EVERY TIME: BullseyeBore Core is a revolutionary drilling guide that solves the problem that every drill user faces: how to drill straight holes perpendicular to the worksurface. It projects circular patterns that show you when your drill is properly aligned. When the patterns are concentric, your drill is perfectly perpendicular, guaranteeing a straight hole. No more guesswork, no more crooked holes! It's a must-have addition to any collection of shop accessories and wood working tools.
- STANDARD RED LASER MODEL: The CR1-100 is the standard red laser version of BullseyeBore Core, featuring two long battery life 650nm (Class 1, ≤ 1mW) red laser patterns: one fixed Reference Pattern and one variable Alignment Pattern. It supports standard drill bits from 2" to 5" and provides significantly longer battery life compared to green laser models, making it ideal for extended indoor use and applications where frequent battery changes are impractical.
- WORKS IN ANY ORIENTATION: BullseyeBore Core works effortlessly on walls, floors, ceilings, or boards at any angle - unlike drills with bubble levels that rely on gravity. The Core's unique design ensures perfectly perpendicular holes regardless of position, giving professionals and DIYers alike the freedom to work on any surface with confidence.
- UNIVERSAL DRILL COMPATIBILITY: BullseyeBore Core is a simple drill accessory that attaches magnetically to thousands of common commercial drills in seconds. Simply connect it to your drill chuck's face and you're ready to drill perfectly straight holes immediately. The quick-attach design lets you switch between drilling with and without alignment guidance in moments. Not compatible with Rotary Hammer Drills.
- ENGINEERED FOR SAFETY: If BullseyeBore Core contacts any object during operation, its magnetic connection instantly breaks, stopping its rotation while allowing the drill bit to continue spinning safely. Its unique shape becomes virtually invisible during use, providing unobstructed visibility of both the drill bit and work area throughout operation.
- NON-CONTACT OPERATION: Unlike traditional drill blocks and drill jigs, BullseyeBore Core never needs to touch your worksurface, eliminating scratches or marring. It gives you a clear view of both your drill bit and the worksurface throughout the entire drilling operation, ensuring precision results for DIYers and professionals alike.
