Useful instructions: a suitable lubricant helps to extend the service life, reduce friction and increase the quality of the hole and thread. Before making a thread, drill a hole with the correct drill size. The tool must be properly aligned with the workpiece and have enough room for the chips to be removed. The correct speed and pressure must always be maintained.
