Corner
Round Router bit

The
corner-rounding bit rounds an edge to a given radius. The tool is shouldered to
cut a fillet if required. The cut can be used to ease edges, as a simple profile,
or as a part of a complex one. Other names for this router bit are round-over, rounding
over and quarter-round. If a smaller pilot bearing is used, a second shoulder can
be produced, in effect making the bit a beading bit.

Rounded edges give a project a softer, smoother look. The greater the radius
of the round-over, the more pronounced this effect becomes.

Rounding
an edge makes it more durable because it won’t show dents, splinter, or lose its
finish as easily as a sharp corner. Like a blade that loses its sharp edge, a rounded
corner is more ‘friendly’ to people or objects that come in contact with it.

Manufacturers classify round-over bits according to the radius they cut. So,
a ³/₈ inch round-over bit cuts a ³/₈
inch radius, and so forth. To determine the radius of a round-over bit, measure
either of the dimensions shown in the drawing.
