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

Enlarge existing hole diameters: Using the Drill & Drop holder makes it very simple to enlarge a hole by adding another hole collector. The small hole collector, which is pushed onto the hex shank from the back, serves to center it. The enlargement is then done with the larger hole collector that is slid over it.
