1. A rotary cutting tool comprising:
an outer shaft having a proximal end and a distal end;
a drive shaft disposed within the outer shaft and extending between the proximal end and the distal end along a longitudinal axis, the drive shaft being rotatable relative to the outer shaft about the longitudinal axis;
an articulating support housing coupled to the distal end of the outer shaft and pivotable relative to the drive shaft between a non-articulated position and one or more articulated positions;
a rotary cutting bit coupled to the articulating support housing and pivotable with the articulating support housing and relative to the outer shaft about a constant velocity joint formed between the rotary cutting bit and drive shaft and positioned along the longitudinal axis;
a connecting portion connected to the distal end of the outer shaft and pivotably connecting the articulating support housing to the outer shaft, wherein the connecting portion is fixed relative to the outer shaft; and
a longitudinal structure disposed between the outer shaft and the drive shaft and engaged with a groove in the articulating support housing, wherein the longitudinal structure is translatable relative to the outer shaft such that translation of the longitudinal structure relative to the outer shaft causes articulation of the rotary cutting bit about the constant velocity joint, and wherein the longitudinal structure extends through the connecting portion and is translatable relative to the connecting portion.
