Amana Tool 49706 Carbide Tipped Plunging Round Over 1/2 R x 1-3/8 D x 1 Inch CH x 1/2 SHK Router Bit

This bit creates a flat-bottom groove between two quarter-round shapes. Short vertical walls extending below the radius lend extra depth to the appearance. Depending upon the cut depth adjustment, the radii can be flush with the work surface or recessed. The profile can be formed on an edge using an edge guide or, on the router table using a fence.
