The N400 and N600 refer to different grit sizes in sandpaper. N400 has a finer grit, ideal for smooth finishes, whereas N600 is even finer, often used for ultra-smooth surfaces or final polishing. Selecting the right grit depends on the project's requirements: start with N400 for detailed sanding and move to N600 for a polished finish.
