When to choose it

The 1918 is useful when an edge detail calls for a 3/8-inch axial cut and a 3/8-inch radial depth in the listed bearing configuration. Those dimensions describe two directions, even though the numbers happen to match.

Choose a different cutter length if your stock calls for a narrower slot. Whiteside describes changing the bearing size to vary cut depth. Confirm the bearing specification separately before relying on a different depth.
