When broaching in multiple passes, shims are necessary to ensure full keyway depth. Slide them between the broach and bushing to set the depth of the keyway.
Note: Broaches have a style designation of A, B, B1, C, D, or E. For proper fit, broaches, bushings, and shims used together must have the same letter designation.
