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.

Problem-free extreme scrab bore drilling: 1. Release the hole collector using the button on the adapter and pull it back. 2. Pre-drill scrab bores 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 scrab bore size.

Enlarging existing hole diameters: Using the Drill & Drop holder makes it very easy to enlarge a hole by simply adding another hole collector. The small hole collector, which is pushed onto the hex shank from the back, serves for centering. The enlargement is then achieved by sliding on the larger hole collector above it.
