The ergonomic curved mouth on this twisted dee bit, offers better acceptance and relief from direct tongue pressure. The hand polished, twist is generous measuring 10mm in diameter making it less severe than a traditional single twist. Large hunter dee cheeks help to stabilize this bit while improving turns. This bit is comfortable and yet has a little “extra” there if you need it. One of our personal favorite bits, it’s available in 5″, 5.25″ and 5.5″
