Where should the drill stop be set according to assembly practices?

Setting the drill stop beyond the far side of the material ensures that the hole is fully drilled through the material, preventing issues such as incomplete holes and potential damage to the workpiece. This practice helps to avoid "coring," where the drill does not break through the far side, leaving material that could interfere with the fitting or function of assemblies.

By positioning the drill stop beyond the far side, the mechanic can ensure that the drill will exit the material cleanly, allowing for proper hole size and depth necessary for subsequent assembly or fastener installation. This technique also minimizes the risk of the drill bit binding in the material and facilitates easier chip removal, resulting in a cleaner and safer working environment. Such attention to detail in setting the drill stop aligns with the precision standards required in aerospace assembly processes.
