Accessory Bundle

Save 10% when you get all three essential BullseyeBore Core accessories together. The Accessory Bundle includes the Standard Chuck Alignment Guide Pack (9-piece), Chuck Extension Pack (3-piece), and Worksurface Extension Plate. 

• STANDARD CHUCK ALIGNMENT GUIDE PACK (9-PIECE): Required for hex shank chucks and small chuck faces, and highly recommended for most standard chucks. Provides precision centering of BullseyeBore Core on the chuck face for improved balance, rotational stability, and prevents slippage during drilling. Includes 9 guides in sizes from 0.70" to 1.10" to fit various chuck diameters. Learn more about Standard Chuck Alignment Guides.
• CHUCK EXTENSION PACK (3-PIECE): Recommended for drill bits 4" or longer and specialty bits like Spade and Auger bits. Particularly useful with CR1-100 and CG1-100 models. Mounts between the drill chuck and BullseyeBore Core to bring laser patterns closer together for easier visualization and reduces pattern diameter for tight spaces or narrow materials. Includes three lengths: 0.525", 1.0", and 1.5". Learn more about Chuck Extensions.
• WORKSURFACE EXTENSION PLATE: A 6" diameter light grey aluminum plate that extends narrow worksurfaces like 2x4s and 4x4s so both Reference and Alignment Patterns remain fully visible. Can be held in place or tacked down during drilling operations. Essential for maintaining pattern visibility on limited surface areas. Learn more about the Worksurface Extension Plate.
• ACCESSORY ONLY: This is an accessory and does not include BullseyeBore Core.
