Will a flush trim bit plow thru or trim one edge only?


please excuse my relative newbieness.
Could you use a flush trim bit to cut directly through a material,.or are they for just trimming off a little from one edge of the cutter only. I'm back to thinking of how to cut the 1-3/8" hollow-core 6-panel textures masonite doors again, now that I have them. They'd have an end, say 1" of (soft?) wood, then the two faces of the textured panel, some cardboard possibly, then another end, say 1" of wood. If I got a bit w/ 1-3/8" depth of cutter, could I use that against a straightedge. One problem I could think of is wander. If I were (or even could), would an end bearing or top bearing be best?
I have had to re-read the answers to my previous post, now I've had time, and I'm still absorbing it.

Assuming it's a trim bit with a bearing, you can plow through *only* if the bearing is not riding on anything as you're cutting. If the bearing is riding on an edge, it can only be used for trimming flush.

Use a collar and a straight bit. Spiral for better cutting. The collar follows your pattern, and where thick is a problem, can form the bearing surface for a flush-trimming bit used from the opposite face.
