A:  Hello John, the blades are not replaceable. - Milwaukee Tool, Social Team

A:  The black cylinder that clips onto the bottom of the shield has a spring in it.  Center the pilot bit on your mark and push the drill and bit gently up until the bit assembly starts to push away from the shield and engages the ceiling/whatever.  Push slowly to make then cut and allow the spring to retract the bit after you break through.  It makes sure that the shield is pressed up into the surface of the cut and seals it as much as possible without requiring you to use two hands on the drill.
