12" x 8" Airplane Groover 1" Bit without Bracket

12" x 8" square end, 1" bit depth, 1/2" bit width, and 1/4" radius double bit airplane groover made of high-quality cast aluminum blade only. By jointing concrete with the airplane groover, you are giving the concrete a place to settle without leaving cracks through your concrete slab. Unless you will be cutting your joints later with a walk behind saw it can be finished with this groover when you are finishing a fresh slab. Handle and Bracket Not Included.
