We have a left hander in my lab and was wondering if anyone might have info as to where I might find left handed burs?

I'm needing to find left handed burs. It seems that there should be some company out there that has LH burs. Mandrels I've found. Also if anyone has any experience with LH high speed air turbines, could you please explain how to retrofit it for a LH'er? Thanks.
