The T3216 Hole Enlarging Adaptor is a double threaded adaptor that allows one holesaw to be nested inside another for the concentric enlarging of existing holes. The smaller holesaw runs inside the existing hole to guide the cut while the larger holesaw enlarges it on the same centre, and the double thread accepts any size of holesaw.
Features:
- Nests one holesaw inside another for concentric hole enlarging
- Keeps the enlarged hole on the same centre as the original
- Double threaded to accept any size of holesaw
