Shoulder Milling Cutter Line Expanded With Additional Sizes

Walter USA LLC has extended the Xtra-tec XT M5130 shoulder milling cutter line by adding 29 new inch sizes, increasing its offering to 119 tools. The extension of the inch line covers cutters using the 09, 12 and 16 mm insert sizes. The M5130 bodies using the 09 mm insert have added new sizes from 0.5 to 1.5 in., the M5130 bodies using the 12 mm insert is expanded with additional sizes from 1.0 up to 5.0 in., and the M5130 bodies using the 15 mm insert adds more choices from 1.0 to 2.0 in.

When designing the cutters, instead of further reducing the clearance angle for the benefit of the cutting force, Walter made it larger and rotated the position of the indexable inserts by 8° so that the effective clearance angle stays the same. As a result, the stability and process reliability of the milling cutters and inserts has significantly improved.

In addition to shoulder milling, the tool is suitable for face milling, ramping, pocket milling and circular interpolation. The primary applications include machining steel, stainless steel, cast iron, non-ferrous materials and materials with difficult cutting properties (ISO P, M, K, N, S and H material groups). Targeted industries include mold and die, energy and general mechanical engineering.

The M5130 cutter has a 90° approach angle, which dramatically decreases the need for a finishing operation. Each size is available with multiple pitches for different applications and features a stable cross section due to the modified installation position of the inserts.

The design of the Xtra-tec XT M5130 means that not only is it more stable and therefore more reliable than competing shoulder milling cutters, but it can also be used with higher feeds per tooth. Combined with the high number of teeth, end users see a significant increase in productivity. Overall, the tool is available in diameters of 0.5 to 6.0 in. with nine unique geometries and eleven grades, including PCD.
