Timberline 320-22 Carbide Tipped Corner Rounding 1/4 R x 1 Inch D x 1/2 CH x 1/2 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.
