CORNER ROUNDING 7/8' X 3/8' (3/16' RADIUS) 1/4' SHANK

Corner 
Round Router bit


Carbide 
Tipped

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 knife 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
6,35 mm shank (shaft) that will fit most small or large routers. 
Please ensure that you select a router bit with a shank (shaft) size that will 
fit into your router collet.
