CU-6 / CU-7 Curling Dies
          The CU-6 and CU-7 curling die sets a useful in forming 
			  larger diameter curls in three strokes. Three operations used in 
			  conjunction with both die sets will produce a closed curl, while 
			  an open curl up to 180-degres can be formed with just the CU-6. 
			  Both die sets may be placed next to each other for progressive 
			  forming.
