Forstner bits are the best choice for drilling precise, flat-bottomed holes in wood. The radial cutting edges shear wood fibers at the edge and bottom of the hole, creating a smooth bore with an exact diameter. The Kik Forstner bits from TG Tools actually have nine cutting edges, which permit cutting curved paths, channels, routing and milling in wood and plastics. They can cut on the edge of a block of wood to create channels, and can also be used to create overlapping holes. The Kik bits also come in a nice, dovetailed wooden box to protect the cutting edges.
