Timberline 320-56 Carbide Tipped Corner Rounding 7/8 R x 2-1/4 D x 1-1/4 CH x 1/2 Inch SHK w/ Lower Ball Bearing Router Bit

The basic edge-forming bit, the corner-rounding bit rounds an edge to a given radius. The tool is shouldered to cut a fillet. The cut can be used to ease edges, as a simple profile, or as a part of a complex one. Also known as roundover, 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.
