A woodworking project is only as strong as its joinery, so precision doweling is vital. This dowel bit set from Task Tools features precision ground cutting edges for super accurate dowel holes that'll hold tight for a fine finished product. Wide flutes transport dust and debris out of the hole for positive contact between the cutting edge of the bit and the wood, which ensures optimal smoothness. Tasks True Centre tip gives you pinpoint accuracy for proper alignment of work piece edges. The bit works in both wood and plastic. Includes bit sizes: 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2-Inch.
