BullseyeBore Core Red CR1-101

- Premium red laser model for 2"-8" drill bits (5.1-20.3cm)
- Optimized for 9+ hour battery life
- Projects three circular patterns (1 Reference, 2 Alignment)
- Works with some specialty bits
- Indoor use only

Detailed Description
  • 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.
  • CLEAR SIGHT LINES: Unique low-profile design provides unobstructed views of both drill bit and work area throughout operation, ensuring precision from start to finish.
  • INDOOR USE ONLY: Optimized for workshop conditions with extended battery life for long work sessions. Does not work in direct or indirect sunlight.

How Does BullseyeBore
Core Work

ALIGNED

The Reference Beam is projected parallel to the drill bit. It creates a circular reference patter non the work surface as your drill rotates. The beam is circular and unchanging even if the drill is tilted or misaligned when working on a flat work surface

MISALIGNED

The Alignment Beam is also circular when the drill is aligned with a flat work surface. However, unlike the Reference Beam, the Alignment Beam Pattern will distort into an elliptical shape when the drill is misaligned/tilted on the flat work surface. To get your holes straight both Beams need to be circular and aligned (concentric)
