NOT JUST A BIT - It's an "adjustable" mouth bit!! Brand New design!
No more mistakes in buying the wrong size, less to have hanging around on your tackroom wall.
This innovative new bit adjusts to precisely fit any size mouth from 4-1/2 " to 5-3/8". Simply twist the shanks in opposite directions and the bit size increases or decreases. No tools required. A simple concept that works.
