Starting Tap

After tap drill size hole has been made, hold piece securely with hole in upright position. Apply good grade if cutting oil to tap. If using large tap wrench, grasp wrench with both hands near the tap and place tap in hole. (Grasp smaller wrenches with hand directly over tap). Press down and start tap clockwise into hole, turning tap forward. When resistance is felt, relieve by turning back to break chip. Make sure tap is square with surface of the work.

	Holding Tap Wrench after Thread is Started
	Once the thread is started properrly, the tap will draw itself into the work. A downward pressure is no longer needed. Grasp wrench by both handles and with slow steady movement continue turning tap into hole. When resistance is felt, relieve by turning back to break chip. Do not force tap.

Starting Die

Before cutting threads on rod or pipe, grind or file small bevel on edge of piece to be threaded. This makes starting easier. Place die in stock with size marking visible. Tighten set screw(s) in die stock. Adjust die stock guide by turning cam plate so that guide pins are against work to be threaded. Fasten work and apply good grade cutting oil. Grasp die stock with both hands near the die and place tapered side of die over end of rod or pipe. Press down firmly and work die back and forth, just as you work a tap.Be sure die goes on squarely.

	Holding Die Stock after Thread is Started
	After thread is started, grasp die stock by both handle ends and with steady back and forth movement continue turning die onto work, advancing only slightly with each turn. It is no longer necessary to press down because the die will draw itself onto the work when turned.
