Professionals Choice O-Ringi Half and Half Bit

Professionals Choice O-Ring Half and Half Bit

This O-ring is made out of 5/16" diameter material.  2 7/8" outside diameter against the extra weight in the compactness of the ring allows for a more stable feel and quick release. The two-piece half and half mouthpiece combine a twisted wire bar piece and smooth mouth across the tongue.  This mouthpiece is softer than a complete twisted wire.
