Thecorner-rounding bit rounds an edge to a given radius. The tool is shouldered tocut 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, roundingover and quarter-round. If a smaller pilot bearing is used, a second shoulder canbe produced, in effect making the bit a beading bit.
Rounded edges give a project a softer, smoother look. The greater the radiusof the round-over, the more pronounced this effect becomes.
Roundingan edge makes it more durable because it won't show dents, splinter, or lose itsfinish as easily as a sharp corner. Like a blade that loses its sharp edge, a roundedcorner 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 3/8inch radius, and so forth. To determine the radius of a round-over bit, measureeither of the dimensions shown in the drawing.
