This is a revolution in brazing technology, delivering high precision and consistency in creating fittings perfect for brazed joints. Using compressed air and an adjustable depth stop, it quickly modifies fittings up to a 1/8th inch thick, providing a seamless transition from a solder joint fitting to a brazed-joint fitting in under 30 seconds.  For fittings over 3-inch size, you will need the SuperDimpler since they exceed the 1/8th inch thickness limit.
