Drilling out design in Carbon fiber

I have a pretty standard carbon fiber clutch cover. I work at a dental office and have every drill with carbide drill bits of every sort. I want to drill my own design but dont want to leave fraying/un-clean edges where ive drilled out in the front of the carbon fiber clutch cover.
Any help?
Thanks.

i think most carbon parts are molded with cutouts, etc and not cut afterward.
it cuts pretty much like fiberglass, you will prob need to re-clear/seal edges.
and carbon dust can kill you....be careful

drilling carbon requires a lancer bit. its life a revolving blade that cuts the weaves to give a proper hole.

Anyone have any 1st hand experience?

Holes would be nice but I want to cut out more than holes. The drill i use in the dental office rotates at 200k rpm. The drill bits I use are either carbide or diamond coated burs.
Id hate to ruin a really nice carbon fiber clutch cover, but is it the only way?

sounds like you've got the right tools. it will probably take 200k rpm to avoid any little fuzzy edges.
give it a shot! if you don't like it they aren't that expensive to replace.

I work in an aerospace factory manufacturing carbon fiber components for aircrafts. To drill though our carbon fiber (which are structural components) we used lancer bits at around 15-20k rpm. That by hand. I'm not sure what our CNC does to drill though it.

Did this ever happen or did it get put aside? i was gonna say the tool you describe sounds like it would do the job but i would still sand the whole thing down after and reseal it with some sort of spray on clear coat. You know to keep the edges clean.

Monster Hooligan.

All take heed to Monster Hooligan's advise. Machining /working with Carbon Fiber or CF. The dust is a poison. Wear a dust mask at the least if machining-grinding-sanding etc.

Merry Christmas everyone!
