I just used the large hole saw to drill through my door and it worked great. Now I have to use the small hole saw and the mandrel-pilot bit will not fit into it. What should I do?

The large hole saw has an adapter in it. When using this hole saw first, the adapter may tighten down on the mandrel when removed. Remove the adapter from the mandrel and it will work in the small hole saw.
