Cut a quarter-round shape bounded by fillets, known as a bead, in one pass by this bit. The width of one fillet is set by the pilot bearing size, with the other is controlled the depth of cut. A beading bit can be transformed into a corner rounding bit by changing the bearing (and vice versa.)

• D-bit width = 7/8"
• B-blade height = 1/2"
• d-shank diameter = 1/4"
• L-overall bit length = 2"
• R-radius = 3/16"
