These bits will be your "go to" bits after you try them one time. The quality if the carbide is tops in the industry and overall construction of the bits can't be beat.
Klingspor's Multi Rabbeting bit set comes with interchangeable bearings to rabbets of different depths. They will produce super smooth cuts on both surfaces of the rabbet. Can be used in joining boards or for letting in back panels. Depth of rabbet can be changed by changing the bearing.
