RBN-831-1050 Stagger Tooth (Single Flute) 1/2"d Sink Cutout Bit

Stagger Tooth (Single Flute) Overhang Cut-Out Bit, 1/2" CR, 1" CL, 3/4" Delrin Bearing (RBN-831-1050 BEA) The RBN-831-1050 updates the popular RNB-831-1150 for longer bearing life with faster, better sink cut outs! Then New RBN-831-1050 only removes 1/2" of material greatly reducing the drag of the cut, the amount of dust being produced, and speeds up the process immensely. The Delrin Bearing sleeves a 1/2" steel bearing. Because the effort needed to remove the sink cutout due to the single flute cut, the bearing rolls on the side of the sink effortlessly reducing the pressure and friction that sometimes causes the bearing to fall apart. If (which should never happen with proper bit maintenance) the sleeve were to fall of, the 1/2" bearing will not allow the cutter to cut into the sink! This is a great improvement over past cutout bits and you are sure to notice the difference! This bit leaves a 1/8" overhang.
