Craftsman router 315.175050 depth adjustment
I am a newbie - I've used this router for a couple of simple projects. There is something about the design of the depth adjustment that I don't understand. At its minimum depth, the tip of the collet goes nearly 1 1/4" in from the base plate. At the maximum depth, the tip of the collet barely reaches the base plate.
Given that most bits' cutting edge projects only 1/2" from the collet when fully inserted, I don't see why it has to go in another 3/4". One problem I am facing is that when I use a 1/4" (length) slot cutting bit with a bearing to cut a tongue and groove on a 3/4" plank, I can't cut the lower groove because the cutting edge of the bit doesn't extend 1/2" beyond the base plate at maximum depth to cut the lower 1/4". The plank has only one flat surface so I can't flip it over to cut the second groove. Is there any way to fix this? Perhaps by inserting a collet extension? I guess inserting the bit halfway into the collet is dangerous so that's not a solution.
Another question, are slot cutting bits available where u can put the bearing either below or above? This would also give me an additional 1/4" of depth.

Reason: Realized that collet extensions are available
