15. A router comprising:
-
a housing; a spindle assembly at least partially housed by the housing, the spindle assembly supported for rotation about an axis, the spindle assembly including a plurality of detents each extending in a radial direction toward the axis, at least two detents disposed in spaced relationship less than one hundred eighty degrees from each other with respect to the axis of the spindle assembly; and a spindle lock assembly including a button member, a mount, and a biasing member that biases the button member away from the axis, the button member including a cap with an outer surface and a pin, the mount coupled to the housing and including an outer surface that is concavely contoured generally toward the axis, the button member supported for movement relative to the mount toward the axis to cause the pin to selectively engage at least one of the plurality of detents to lock the spindle assembly against rotation about the axis, wherein the outer surface of the cap is surrounded by the outer surface of the mount, wherein the outer surface of the mount is disposed at least at a first minimum radial distance from the axis, and at a maximum displacement of the cap relative to the mount toward the axis, a radial distance from the axis to the outer surface of the button member is at least approximately equal to the first minimum radial distance.

16. A method of rotating a collet nut relative to a spindle assembly of a router, the method comprising:
-
locking the spindle assembly against rotation about an axis with a spindle lock assembly, the spindle assembly including a plurality of engagement members, at least two engagement members disposed in spaced relationship less than one hundred eighty degrees from each other with respect to the axis, wherein locking the spindle assembly includes selectively engaging at least one of the plurality of engagement members to lock the spindle assembly against rotation about the axis; operatively coupling a removal tool to the collet nut; rotating the removal tool within a predetermined zone of rotation less than one hundred eighty degrees about the axis in a first direction to rotate the collet nut with respect to the spindle assembly; releasing engagement between the spindle lock assembly and the spindle assembly; rotating the removal tool, the collet nut, and the spindle assembly within the predetermined zone of rotation about the axis in a direction opposite to the first direction; re-locking the spindle assembly against rotation about the axis with the spindle lock assembly by engaging the spindle lock assembly with another of the engagement members; and rotating the removal tool within the predetermined zone of rotation about the axis in the first direction to further rotate the collet nut with respect to the spindle assembly.
