Wood Owl's self-feeding wood boring bits have up to a 50 percent wider cutting tooth surface for added stability and truer holes. The chamfered back edge makes it easier to extract the bit from the work. Other features include a machined lead screw with burr-free threads which helps feed the bit through wood at a consistent rate, a machined straight shaft for concentricity which eliminates wobble leaving a truer hole, the quick-change shank allows fast, secure change outs, and the heat treated metal provides bit durability. The 4-piece set includes sizes 1-3/8, 1-1/2, 2-1/8, and 2-9/16 inches. The 8-piece set includes sizes 1, 1-1/8, 1-1/4, 1-3/8, 1-1/2, 1-3/4, 2-1/8, and 2-9/16 inches plus a 5-1/2 inch extension.
