What is the drill bit length range supported by BullseyeBore Core?

In general, the BullseyeBore Core products are designed for drill bit lengths from 2.0” to 8.0”. While longer drill bits can be used, the resulting Alignment Pattern (or Patterns) on the work surface may be too far from the Reference Pattern for use. A common solution for longer bits is the integration of a Chuck Extension, which is designed to reduce the Alignment Pattern size with longer drill bits. Moreover, if the work surface area is small, integration of a Work surface Extension Plate may also assist with pattern visualization. See the FAQ for Can the extended versions of BullseyeBore Core operate with drill bits longer than 8”? for more information on BullseyeBore Core and drill bits longer than 8”.
