What are Chuck Extensions and what are they used for?
BullseyeBore Core Chuck Extensions are an optional accessory in the BullseyeBore Core ecosystem that fits between the drill chuck face and the back of BullseyeBore Core.
Chuck Extensions serve to move BullseyeBore Core forward along the drill bit and are typically utilized to move BullseyeBore Core’s projected Reference and Alignment Patterns closer together on the worksurface at the start of drilling, which can make drill alignment or misalignment easier to visualize. They can also be used to reduce the overall diameter of the Alignment Pattern (or Patterns) if they do not fit on the worksurface.
The example below depicts a 5.75” drill bit and the resulting patterns at the start of drilling both with and without a Chuck Extension.
Core Green Extended with a 5.75” bit without a Chuck Extension
Core Green Extended with a 5.75” bit and a 1” Chuck Extension.
Note how the Fixed Reference Pattern and Alignment Patterns are closer for easier alignment or misalignment interpretation.
The example below depicts a 7” drill bit and the resulting patterns at the start of drilling both with and without a Chuck Extension.
Core Green Extended with a 7” bit without a Chuck Extension
Chuck Extensions are offered in size incremental lengths of 1.50”, 1.00”, and 0.50”.
Core Green Extended with a 7” bit and a 1.5” Chuck Extension.
Note how the Fixed Reference Pattern and Alignment Patterns are closer for easier alignment or misalignment interpretation.
