With the introduction of the Xtra·tec XT M5137, Walter introduces a shoulder milling cutter that brings with it incredible benefits for machining ISO-P and ISO-K materials. Firstly, users benefit from double-sided indexable inserts with six usable cutting edges. This provides an attractive price-to-cutting edge ratio. Secondly, the milling cutter has an approach angle of 90deg and is capable of ramping, circular interpolation milling and pocket milling.

This combination is something that is completely new to the market. Following on from the successful launch, Walter is now expanding its M5137 range to include the new G27 indexable insert geometry for universal use. While the G57 geometry that was previously available, primarily excelled in average to good conditions with low cutting forces and average feeds such as pre-machined workpieces, the sintered G27 completes the Walter range. The geometry can be used for challenging jobs as well as unstable clamping arrangements, interrupted cuts or forged skin.

Both geometries are suitable for face milling, shoulder milling and pocket milling, as well as circular interpolation and ramping in steel and cast iron workpieces, and in stainless and difficult-to-cut materials. The Walter range now includes the cutter body with bore adaption and Weldon shank. It is also available in new inch-diameters from 1 to 4in. The high process reliability and cost-efficiency achieved through low cutting tool material costs and the wear-resistant Tiger·tec grades make the milling cutter a particularly good choice for users producing mid-range quantities.
