Is it possible to tap a hole twice in a HMC using the M29 rigid tapping mode, or will the tap crossthread when it enters the second time?

When I am doing one off type work or very small series of parts with threaded blind holes, I usually thread just a few mm`s into the hole with the machine, and re-tap it by hand later to keep chips from packing infront of the tap and break it.

If I could peck-tap the hole in the machine, then that would be alot easier.
