Fixed & slip renewable bushes are used where more than one operation is performed in the same hole of the component, such as drilling, and then reaming or counterboring. They are used in conjunction with liners due to their body O.D.'s being ground to a correct slip fit, enabling quick installation and removal. The renewable bush is held in place by a locking screw - but can be easily removed with a 45° turn.
