Ten Basic Router Bit Shapes

Router bits can be used with fixed base routers, plunge routers and shapers to apply edge shapes to wood stock.

A beading bit is similar to a roundover bit (below) in that it applies a rounded shape to the edge of the stock.

Beading bits often have a bearing tip for riding along the edge of the stock as it is cut.
