Chuck it into a router table or handheld router to flute columns, cut finger pulls, and rout rounded channels. The balanced bit runs true at speed, so cuts come out concentric and clean with minimal sanding afterward.
Whiteside Machine Company manufactures its router bits in Claxton, Georgia, and is consistently rated among the top-performing router bit makers in independent woodworking tests.
