I have deburring tool, with replaceable blades. The blade has a grove
in it and the tool has a ball to engage the groove:

It would seem that the collar would be spring loaded against the ball &
one would change cutters by pulling back the collar, releasing pressure
on the ball & freeing the cutter. BUT, my collar's spring pushes it
*away* from the ball, as shown in the pic. Pulling it forward to the
ball bottoms out before pushing on the ball.

Am I missing something, or is it broken?

Thanks,
Bob
