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. Bit #49519 max RPM is 28,000. Bit #49520 and 49521max RPM is 22,000. Bit #49522 max RPM is 18,000. Bit #49523 and 49524 max RPM is 16,000. Bit #49526 max RPM is 15,000. Bit #49522, 49523, 49524 and 49626 are for use in table-mounted routers only.
