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 PERFECTLY STRAIGHT EVERY TIME: Projects three bright red laser patterns that instantly show when your drill is perpendicular to any surface. When the circles align concentrically, you get a straight hole every time - no guesswork, no crooked results. EXTENDED BATTERY LIFE RED LASER TECHNOLOGY: Features long-lasting 650nm red laser with one fixed Reference Pattern and two variable Alignment Patterns, providing significantly longer battery life than green laser models. Perfect for extended indoor use and applications where frequent battery changes are impractical. Supports drill bits from 2" to 8" including specialty bits (Spade, Auger, Forstner, Step, and Aircraft bits). UNIVERSAL COMPATIBILITY & INSTANT SETUP: Magnetically attaches to thousands of common drill chucks in seconds. Switch between guided and unguided drilling instantly - no tools required. Not compatible with Rotary Hammer Drills. WORKS IN ANY ORIENTATION: Unlike gravity-dependent bubble levels, works flawlessly on walls, floors, ceilings, or angled surfaces. Perfect for overhead work, vertical drilling, and awkward positions. SAFE & NON-CONTACT DESIGN: Magnetic connection breaks instantly if contacted during operation, while your drill bit continues safely. Never touches your workpiece - no scratches, marks, or damage. INDOOR USE ONLY: Optimized for workshop conditions with extended battery life for long work sessions. Does not work in direct or indirect sunlight. GO-TO DAD GIFT: This is the ideal Christmas or birthday gift for men and women who DIY, repair, or create. It's also the perfect gift for men who have everything.
