Router Corner Round 3/8" Radius X 1/2" Shank KP1209 - Protech
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.
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.
This router bit has a 12,7 mm shank (shaft) that will fit most large routers. Please ensure that you select a router bit with a shank (shaft) size that will fit into your router collet.
