The Covell Round-Over dies are a great tool for creating a rounded or radiused edge on a sheetmetal panel. They are available in four sizes - 5/16", 1/2", 1", and 1 1/2" radii. The dies are precision-machined from heat-treated tool steel, and will last a lifetime if given reasonable care. You can see these dies in action on the Beading Machine Basics video on YouTube.
There are two styles of dies – one for the Mittler Bros. machines, and the other for the Pexto 622 machine. With our Sleeve/Spacer sets, the Pexto-style dies can be used on many other popular machines. All dies have 16-gauge mild steel capacity. The Covell Round-Over dies are available exclusively from Trick-Tools.com:
