WH Ultra has the same structure as Sprenger's KK-Ultra with the difference that the center has a unique scroll, which adds to the stimulus and acceptance of the bit.
The bradoon bit is made in Sensogan (Sensogan is a material from Sprenger made on copper, manganiese and zinc for reduced oxidation and better well-being) and is 16 mm thick, with loose rings with 55 mm diameter, can also be used as a single bit as the difference is only the size of the loose rings.
