The inner edge cutting assembly (18) includes a first blade support member (24) having a forward portion (25) defining a conical surface (26). The inner edge cutting assembly also includes a plurality of replaceable blade members 30 mounted on the conical surface 26 for engaging the inner edge (14) of the tube end (12). The outer edge cutting assembly (20) includes a further blade support member (42) having a forward portion provided with a forwardly disposed tube receptor (46) defining a conical sidewall (48). The outer edge cutting assembly (20) also includes a plurality of replaceable blade members (50) mounted on the conical sidewall (48) for engaging the outer edge (16) of a tube end.
