Is there any way to prevent the build up of pitch/resin on a cutting tool? I've seen plenty of advise and methods for removal after the work is done, but what about during? I just completed a set of slots made with a 1/2" end mill. The end mill was building up a pretty good coating of pitch on it. I had to stop and clean it off before finishing.

Is there anything to use on a cutting tool that would prevent or at least slow down the build up of pitch?
