Starrett KA19-N\Oops\ Arbor, Hole Enlargement Arbor
- Replaces the pilot drill in any Starrett A1, A2 or A10 type arbors.
- Replacing the pilot drill, the KA19 allows diameters to be enlarged by attaching a saw of the same size to that of the existing hole.
- This saw then acts as the pilot for the larger diameter saw that is attached to the arbor in the normal way.
