Easily handle extreme shrink holes: 1. Release the hole adapter using the button on the adapter and pull it back. 2. Pre-drill the shrink hole with the centering drill. 3. Then slide the hole adapter forward until it locks in place. 4. The hole can now be drilled in the desired shrink position.

Enlarging existing hole diameters: Using the Drill & Drop holder makes it very easy to enlarge a hole by simply adding another hole adapter.
