I do, but that is inadequate for limiting depth of cut, especially on curved / angled pieces.
The standard 1/16" slot cutter, out of the box, cuts the slots WAY too deep, like twice as deep as they need to be.
What I ended up doing was purchasing a larger bearing separately, and replacing the stock (smaller) bearing on the cutter. That way the depth of cut is always mechanically limited by the slot cutter itself.
