pnut Posted March 2, 2021 Share Posted March 2, 2021 Is there anything special I should know before attempting to grind a ductile iron bottom fuller shank to fit my hardy hole? Pnut Quote Link to comment Share on other sites More sharing options...
BartW Posted March 2, 2021 Share Posted March 2, 2021 It can withstand heat very well; just don't quench it in water. you can grind it fairly hot; but leave it to aircool. if you work ik fysically; it does workharden (become brittle) a bit. from my understanding, ductile iron is a special form of cast iron; which get's it's special abilities from the molecular structure with grafite and such. It's much stronger than aluminium; but much cheaper than forging the same part out of steel. It's somewhat mallable, but to a degree. The dust is also not good for your health in prolonged exposure, so use all the needed PPE; as it does make noticeably more dust, less chips than working steel.
