Default Machining Powdered Metal - ugh!

Cast iron never produces a curly chip. However, you should

Never say never. :-)

Actually there's so many types of cast iron that this statement
isn't true. It depends on the cast iron type and heat treatment. I've
actually produced some pretty good sized curls in really good quality
cast iron. Cheap cast iron on the other hand will usually powder up.


Wayne is correct. Just because "I" never machined a different type
of cast iron doesn't mean none exists. LOL
