Amana Tool 55432 Carbide Tipped Adjustable Straight with Bevel Instile and Rail System 1-7/8 Dia x 11/16 x 18 Deg x 1/2 Inch Shank Set
Bits in these sets have profile and groove or rabbet cutters and ball-bearing guide mounted on a 1/2" shank. Respacing of the components should only be necessary - using the provided shims - after the cutters have been resharpened. Guide straight cuts with the fence; use the pilot bearing only for cuts on curved rails or stiles.
This was the first time I ever used cope and stick joinery. I was very pleasantly surprised that both bits were received with the adjustments for plywood thickness being just a gnat's hair off. They worked beautifally.
