Abstract We study the topology of the boundaries F₅ ∂ F f and F₈ ∂ F I of the Milnor fibers F₅ F f and F₈, F I, respectively, of real analytic map-germs f: \, (RM, 0) (RK, 0) f: (R M, 0) → (R K, 0) and f₈: = ₈ f: \, (RM, 0) (RI, 0) f I: = Π I ∘ f: (R M, 0) → (R I, 0) that admit Milnor’s tube fibrations, where ₈: \, ({R}K, 0) ({R}^I, 0) Π I: (R K, 0) → (R I, 0) is the canonical projection for 1 I 1 ≤ I K. For each I we prove that the Milnor boundary F₈ <mml: mi
