How do I choose the correct size Chuck Extension?

Some experimentation may be required to select the optimally sized Chuck Extension. This may be accomplished by visualizing the pattern on a worksurface with the target drill bit and different size Chuck Extensions installed. Chuck Extensions are offered in size incremental lengths of 0.50”, 1.00”, and 1.50”.

Always read and follow the BullseyeBore Core Safety Guidelines before attempting to use BullseyeBore Core or any BullseyeBore Core accessories on a drill or in an actual drilling operation.
