ABSTRACT:
A power tool and spindle lock. The spindle lock includes a spring and a detent arrangement to control and buffer the rotation of the spindle and to delay the engagement of the locking elements. In some aspects, the invention provides a spindle lock including a spring element which applies substantially equal spring force to delay the operation of the spindle lock when the spindle is rotated in the forward direction or in the reverse direction. In some aspects, the invention provides two spring members which cooperate to apply the substantially equal force to delay the operation of the spindle lock when the spindle is rotated in the forward direction or in the reverse direction.
