Click the hole collector onto the centering drill - ready to go: 1. Pressing the button on the adapter unlocks the hole collector. 2. Slide it forward and replace it.

Lightning-fast removal of the drill core: By pressing the push button on the Drill & Drop hole collector once, the drill core can be removed very quickly and without the need for additional tools.

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

Enlarge existing hole diameters: Using the Drill & Drop holder, enlarging a hole by adding another hole collector is very simple. The small hole collector, which is pushed onto the hex shaft from the back, serves for centering. The enlargement is then done by sliding on the larger hole collector above it.
