Here is a new bit from Mexico that I imported for my outfit. This is what we call a snake bit with a loose jaw San Joaquin mouthpiece. The mouth is 5 1/8" wide and has an 8", long shank, and a 2 1/2" port. There are a couple of minor blemishes that effect nothing. There is a single stripe missing if you look in photo #3. Our logo is -U-. They only stamped this with a U and left off the bars. A great bit anyway. Buyer pays shipping.
