    Calibration Rods

    Also known as calibration standards, these rods let you check and set micrometers and other measuring tools. For accuracy, they’re precision ground to extremely tight length tolerances. They have insulated plastic handles to minimize heat expansion.

    Turn straight and true—use these bars to confirm that your lathe headstock and tailstock are right inline. Insert the bar between the centers of your headstock and tailstock, then use a variance indicator (not included) on the bar ends. Any difference will register since the bar ends are precision ground to within 0.0002” of each other.
