will last a lifetime. Matched cove and bead style bits come fully assembled, so you
can get to work making beautiful rail and stile joints. Mill a tenon of any length
simply by unscrewing the top cutter and bearing of the rail bit from the lower cutter
and shank. Create 1-3/4'' joints for exterior doors or remove the spacers and narrow
to 1-3/8'' for interior doors. Includes coping cutter, stick cutter, wrenches, wood
storage case, and FREE instructional DVD.
