ROUTER BIT CORNER ROUNDING 1 1/8″X1/2″

CORNER ROUNDING 1 1/8″ X 1/2″ (5/16″ RADIUS) 1/4″ SHANK

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.

How to measure the radius 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.
