    Also known as involute gear cutters, these tools work with a milling machine to create 14½° or 20° pressure angle spur gears. If worn, they can be sharpened and used again.
    To select a gear cutter, follow these steps:
    1. Determine the pitch of the gear you're cutting. Gear pitch = (No. of Teeth + 2) / OD. Round to the nearest whole number.
    2. Select the cutter that matches your gear's pitch and number of teeth.
    For 14 1/2° Gear Pressure Angle—Cutters for 14½° Gear Pressure Angle—The former industry standard, these gears are often found in older machinery.
