BullseyeBore Core Standard Chuck Alignment Guides

BullseyeBore Core Standard Chuck Alignment Guides

• REQUIRED FOR HEX SHANK AND SMALL CHUCKS — IMPORTANT BEFORE YOU BUY: If you’re using BullseyeBore Core with a hex shank chuck or a chuck with a small shaped front face, these guides are required, not optional. Highly recommended for most standard chucks to ensure proper centering and consistent performance. Not sure if you need them? Check your chuck’s outermost flat front face diameter against the 9-size range in Bullet 3.
• PRECISION CENTERING THAT HOLDS: Standard Chuck Alignment Guides center BullseyeBore Core precisely onto the flat chuck face at installation, so it stays centered while spinning, not just when you first attach it. The result: better rotational balance, no lateral shift during drilling, and more accurate holes. Especially important for hex shank chucks or chucks with small shaped front faces.
• COMPLETE 9-PIECE SIZE RANGE — ONE FITS YOUR CHUCK: Includes guides in nine center hole sizes: 0.70“, 0.75”, 0.80“, 0.85”, 0.90“, 0.95”, 1.00“, 1.05”, and 1.10", covering the full range of standard drill chuck face diameters. Measure your chuck’s outermost flat front face diameter, select the guide with a slightly larger center hole, and you’re set.
• INSTALLS IN SECONDS — NO EXTRA HARDWARE NEEDED: Measure your chuck’s outermost flat front face diameter, select the right guide from the 9-piece set, and mount it on the back of BullseyeBore Core using the same screws that attach the back face. No modifications, no additional tools.
• FOR USE WITH BULLSEYEBORE CORE — SOLD SEPARATELY: These guides are an accessory for BullseyeBore Core (CR1 and CG1 series), which is sold separately. If you don’t yet have the Core, start there. If you have the Core and use a hex shank chuck or a chuck with a small shaped front face, this is the add-on that makes it work correctly.
