    Texture

    A flat finish, no paste or slurries required—these plates have built-in abrasives to smooth out your workpiece. When you don’t need different abrasive sizes, these are a good choice to minimize mess.
    Use the complete surface of these plates to prevent wear patterns.
    Smooth—Smooth plates make consistent contact with your workpiece for an even finish.
    Grooved—Grooved plates catch and clear shavings to protect your workpiece from scratches.
