Then push the Lochs+AMMApA-ge back forward until it locks. 4. The hole can now be drilled in the desired Schr+AMMApA-position. Enlarging existing hole diameters: Using the Drill & Drop holder makes it very easy to enlarge a hole by simply adding another Lochs+AMMApA-ge. The small Lochs+AMMApA-ge, which is pushed onto the hexagonal shank from the back, serves as a centering tool. The enlargement is then carried out with the larger Lochs+AMMApA-ge that is pushed over it.
