Type TB, Template Drill Bushings











TB type bushings are designed for thin jig plates from 1/16 to 3/8 inch thick.
  Bushings are held in place by a corresponding retaining ring.
  The OD serrations prevent the bushing from spinning.
  Bushings can be removed and reused by breaking the aluminum retainer ring.
  Extra retainer rings may be ordered separately.
