Bits for carbon fiber

[richdav8500]

What are people using to cut carbon fiber parts?

Today I broke my composite bit after about 500 parts ( picture attached ) . I don't know what it is and it doesn't have any writing on it. I was given it by a sales rep that is no longer with the company. I have a bit that looks similar but is not giving the same results. Lots of companies seem to sell several bits that look like this but wanted to see what other were using with good results.

The parts are 0.06 inch think carbon/ fiberglass laminate ( picture attached ). I am just profiling the outer shape.

Thanks in advance for the help.

You can get those from Onsrud. Looks like Series 67-500.

Is not carbon fiber dust very, very dangerous ?

Extremely so! It makes fine needles that have barbs, like fishhooks. You get it in your lungs and it stays!
