I read in a previous discussion someone suggested using graphite powder to prevent punches and drifts from getting stuck in hammer eyes. I was wondering if anyone can comment on their experience using graphite powder / provide advice re usage. The products I've looked at have an upper temp limit of 850f which is well below forging temp for punching a hole in 2" 1045 so not sure if I'm seeing the right product. Also, it's pretty pricey stuff - like 30 - 40 bucks for a small amount. I've seen people use coal dust but I don't run a coal forge and charcoal dust doesn't seem to do much good. 

So ... any thoughts on graphite specifically or other methods to prevent locking up would be appreciated. 

Lots of good discussion threads about punch lube already on IFI -- did you read those first?

Pro tip: the search function in the forum software sucks. Do a google search and include "iforgeiron" as one of your search terms. I just searched on "iforgeiron", "punch", and "lubricant"; the first eight responses were separate IFI threads.

thanks for the reply - i didn't but will now. 

My pleasure.  Remember: the best questions are the ones that show you've done your research, thought about the problem, and still need further illumination.

Note on the above linked thread I've stopped using linseed oil as it eventually dries out and now mix the graphite with grease instead.  It's still $5 per pound at the local John Deere dealer.
