If it's soft gray iron and has the cast skin intact, and is not chilled, you'll have the best luck if you can get below the skin, where wear is minimal. The use of a C2 grade of carbide is recommended for wear resistance. If it's hard in any way, it can prove to be difficult, if not impossible, without grinding.
