Would you recommend the same bit for Sintra (3mm)? I hate removing the "fuzz" from stencils.
Do you have knife cutting options.
For stencils i often do not use the router so i dont have to consider internal tool radius conflicts.
Typical Oscillating tools and drag knifes work quite well with 3mm sintra.
I too hate the fuzz

I picked up one of these, works ok if you're just chopping sheets into blanks, just make sure you know which way the knife will run...
Neat idea, might be worth playing around with a little at some time but I can see how you might need to be careful on the direction. I would guess cutting vinyl it would be less of an issue but a shallow "drag" to orient it before going deeper into the coroplast would probably be the way to use it. I know Vcarve can do drag knife style corners, not sure if that would work for thicker stuff though.

edit: I also would have to get my post to keep the spindle completely OFF.

Most definitely keep it off. That's one of my biggest fears running it, did I set the file up right?
Also it doesn't fit in my atc tool holder, the gantry doesn't have enough clearance to retract after grabbing it, if the long end swivels under the clamps.
Haven't tried it on vinyl, though I did use it to mark .040" aluminum for bends, and though it helped the material make a nice sharp bend, it also caused the aluminum shear apart at the knifed line when the material was handled too much. Kinda surprised the hell out of me.
