Claim 12:
13. A surgical cutting tool comprising:
an inner drive hub coupled to an inner shaft, the inner drive hub further comprising a groove;
an outer hub coupled to a hollow outer shaft, the outer drive hub further comprising a plurality of slots; and
a seal comprising a body and a plurality of tabs extending substantially perpendicularly from the body;
wherein the inner drive hub and the inner shaft are configured for insertion inside the outer hub and the hollow outer shaft such that the groove is positioned proximally to the plurality of slots;
the seal body is positioned outside of the outer hub;
each of the plurality of tabs extends through a separate one of the plurality of slots and into the groove to removably couple the inner drive hub and the inner shaft to the outer hub and the hollow outer shaft;
wherein the tabs cooperate with the inner drive hub to prevent the inner drive hub from being removed from the outer hub without removing the seal; and
wherein if the inner drive hub is pulled outward from the outer hub, the tabs bend and become wedged between the inner hub and the outer hub, thereby preventing the inner drive hub from being withdrawn from outer hub.
