BullseyeBore Core Standard Chuck Alignment Guides are an optional accessory in the BullseyeBore Core accessory ecosystem.
A single Standard Chuck Alignment Guide can be screwed onto the back of the BullseyeBore Core device over the label. Standard Chuck Alignment Guides are designed for two purposes:
- First, they provide a means to consistently center BullseyeBore Core onto the flat chuck face during installation. This makes repeated installations onto the drill chuck face both easy and consistent.
Second, they help to prevent lateral displacement (sliding) of BullseyeBore Core across the flat chuck face. Lateral displacement can occur during initial drill rotation or high-speed rotation, but is most common during electric breaking (e.g., when your finger is removed from the drill trigger and the drill stops suddenly). Some power drills employ a strong electric breaking function that creates an abrupt stop to any drill rotation.
Standard Chuck Alignment Guides are offered in nine different center hole size options of 0.70”, 0.75”, 0.80”, 0.85”, 0.90”, 0.95”, 1.00”, 1.05” and 1.10”. This range of guides provides for the ability to work with a wide array of drill chuck face diameters.
