I apologize if this is too much of a noob question, but I was just wondering about how long your typical router/zip bit will last on a cnc machine cutting into 6061 aluminum. I'm talking about the standard router bit used/designed to cut into metal. How many feet of cuts will one make before dulling? Do you resharpen them or just get a new one?
