Notching and slotting

The depth of a notch and the distance to the hole are measured exactly as the coordinates for two holes.

Lenses with edge thickness of 2.0 – 2.5 mm can be notched by moving the table with the lens on it slowly and carefully against the drill. Notching in this manner can only be done by using our recommended drill bits, since they have a side-cutting edge.

For longer notches, special frasers (fish-tail drill bits) should be used. The soft PVC-pad is a wearing part and can be easily exchanged.
