TUBINGEN, Germany, Jun 19, 2026 – Walter is expanding its milling cutter portfolio with the new Xill·tec Aero solid carbide cutters MC331/MC333 Advance, thereby offering a universal tool solution that is also specifically tailored to the requirements of the aerospace industry. Following the successful launch of the MC230 Advance for steel, Walter now has two specialist cutters in its range – the MC331 Advance (without Chip breaker) and the MC333 Advance (with Chip breaker) – with a clear focus on ISO material groups M and S, and in particular Titanium. The basic principles for their outstanding results when machining aerospace-typical titanium alloys such as Ti6Al4V or Stainless steels such as 316L are the universal grade WK40EA and the geometry featuring Differential pitch, which is specially tailored to these materials. In combination with these elements, it ensures exceptional operational smoothness and surface quality even at high cutting parameters.
Walter offers the milling cutters as five- or seven-flute (z5/z7) tools in metric sizes ranging from Ø 6 to 25 mm, with or without Corner radius or Chip breaker, and with cutting lengths of 2 to 5 × Dc. According to Walter, both tools are equally well suited to dynamic milling with high material removal rates as well as for finishing operations, such as shoulder machining. In addition to the aerospace sector, Walter cites the energy sector and the medical and energy sectors as typical areas of use. Both the MC331 Advance and the MC333 Advance are suitable for reconditioning; the Tübingen-based company offers custom dimensions via the Walter Xpress™ Service. As with the MC230/MC233 Advance, users also benefit from an excellent price/performance ratio, outstanding tool life and high process stability with the Xill·tec Aero.
