Professionals Choice D-Ring Half and Half Bit

This D ring is made from 5/16" diameter material and has an outer diameter of 2 7/8". This D ring is slightly more compact than a normal 3 1/2" D ring. The 5/16" material adds a little more weight which helps the stability and release. The two-piece half and half mouthpiece combines a twisted wire bar piece and smooth mouth across the tongue. This mouthpiece is softer than a complete twisted wire.
