1∕8"-radius Traditional Bead
no. 80-102 (1∕4" shank), $34
We love this bit for table aprons because the bead and recess create a shadow that adds an eye-catching detail to an otherwise plain surface. You can also use this bit on the edge of adjacent faces of a workpiece to create a full-round bead that wraps around the corner.
